Previous question: How hard could it be to take advangate of the multi-cores.
The first thing is that it depends on what you are starting with. If you have zero code out there, you can come up with a nice design for your program that takes advantage of as many cores as you throw at it. If on the other hand you have large chunks of legacy code that was written in the time of single cores, it may be close to a re-write to fully take advantage of the hardware. In some cases it will be easier in some cases to throw the old code away.
But some of it is imagination, if you can look at a problem and the solution you orginaly came up with, and using your imagination look at the problem at hand in inovative ways, parts of the programs could be re-written to take advantage of the hardware and other parts can be left alone (for the short term). This is an incremental step, you gain X% in one area and little to nothing in another area. The key is to determine what your program spends most of it time doing and re-write/re-design that section of the code for the biggest short-term gains.
I remeber working in assembler and selecting the correct combination of instructions based on their function and the number of CPU cycles it took to execute each instruction. Sometimes a set of 12 instructions was faster than a different set of 8 instructions in accomplishing the same result. Use your imagination and look at the problem from a different angle. If your brain only sees a number of serialized steps, you won't be able to come up with anything that takes advange of the hardware.
What you start with (old code) and your imagination can get you there quicker or slower.
Short answer: It depends.

Funny that you say "accurate" color.....
Anyone ever hear of the "Pinkening" of the Apple displays over the last 2 years? If you haven't then you may have seen it on your trips to the Apple Store.
Apple LCDs have had a nasty habit of having a Pink hue to them that you cannot dial out of the display. Granted, Apple has been pretty good at replacing these models, but it has been a major issue to those it has affected.
Yes, I'm quite aware of that issue. I do not mention it because it is an anomaly in the build. Dell also had backlight bleed problems with the 2005ftw units (and by all reports, wasn't handled all that well by Dell).
However which panel each company decides to use in their product is a choice, the results of which will effect every monitor in the line up. Do you see the difference there?
True accurate color will only be had by using color calibration units. So with that rebutle I will say that you will be able to achieve "accurate" color with that $250 LCD monitor from Best Buy.
Yes, but some panels are far more prone to the color shifting with time. Also the evenness of the color/contrast/backlighting has to be even across the entire screen. Color calibration units only measure a small part of the screen in order to create a color profile that your computer will apply to the entire screen. That profile will not help you if the screen is imbalanced.
Dell, quite honestly, doesn't care about the prosumer market. THis is obvious in their recent choice to take their 23" monitor from 8 bits per color down to 6. So instead of 24 bit color, you get 18 bit color which is then dithered to get 24 bit color. For those that don't understand color bit depth,
18 bit = 262,144 colors
24 bit = 16,777,216 colors
Why would Dell do this you ask? Because they can now drop their response time to 6ms from 16ms. That's right, they made a change that severally effects the color quality in order to archive one of the few stats that people use and see to buy a monitor.
There is far more to monitors than ms, contrast, and even color accuracy. There are people in this thread that seem to think that all monitors are created equal but for the case they are put in, or that there is only one component inside the case. To these people of course monitor prices should all be about the same.
Before anyone screams foul on Apple pricing ONE more time I dear you to go to www.NEC.com and check out the different monitors sold by them. You can pay $2000 for a 20" there if you like.
Monitors are just like most computer hardware, not all created equal, not all priced equal. Weigh you needs with your budget, research the product, and make a choice that's right for you. If Apple doesn't offer a choice that fits your equation, that sucks (happened to me), but fortunately there are a hundred other companies out there, one of which might just offer what you require.

iMac is already wildly popular. they have no reason for aggressive pricing.
You must have missed my post on doing the price comparison a la the Mac Pro. I feel they should have to prove the "more expensive" myth wrong CLEAR across the board.

So, how long till it comes to laptops? :D
And on top of that, its only going to be a viewer, right? I mean have they created any Blu-ray burners, yet?
I really don't want to buy a Macbook Pro until it has Merom, 802.11n, and blue-ray, cause I know those are all going to be standard in less than a year and I can't afford to have a crippled laptop for 3 yrs.
Hopefully it won't be too far, I've saved enough cash.
all going to be standard ? how long did it take for wireless g and dvd burners to become standard? :rolleyes:

Juxtaposition of medical apps to a simple preschool numbers trace shows the broad appeal and power. Sorry competitors, if you think this is just about a web browser on a tablet you clearly have no vision. Apple is yet again skating to where the puck is going.
Also - Peter Coyote's voice always adds gravitas.

touch screen is usefull for mobile devices because you don't have any place to put a screen, mouse and keyboard. But desktops you have room for keyboard and mic so i don't see this happening in imacs.
Steve said a D8, he believes that there will always be a place for desktops but a majority of our tasks will be done from tablets or mobile devices that are touch screen enabled.
And there are just some things that require keyboard and mice! steve acknowledges that and so does the rest of the world.

Come on guys...give the guy a break,stop making fun of him...this is the case he needs.
How open minded of you...
Ive been contemplating this keyboard because of the same reasons. I have a question for anyone that can answer this...I use the new Logitech Performance MX, which uses the same mini usb connector, can I use that to connect the keyboard as well, or do I have to add a second USB connector for the keyboard?
According to the Logitech website, the Performance MX mouse uses the Unifying receiver and these products are compatible with it (http://www.logitech.com/en-us/349/6126?pcid=6072), but not the Logitech diNovo Mac Edition Keyboard.

Perhaps Microsoft should have a "switch" campaign like Apple for the Zune. Showing all the wonderful things like radio and squirting music and photos.

Why is a congressman getting involved in this? So ridiculous. This information has been stored by the cell companies for years. Now I can access my own. So what.
And all this worry about being hacked or someone else looking at my computer. If they take my computer they can also see a ton of other personal stuff about my life. Just like stealing or going through my wallet.
This is just the media blowing something out of proportion to make a story. So dumb.

Talking about new "features": have you noticed the Fuji wallpaper is different?
The new one has clouds at the base...
I'd like to see this too! The old one was pretty bland at the bottom so if this is true I'm glad they changed it.

hello everyone..i have bought a new ipod touch and i want a case to cover it and to provide protection from scratches.please can anyone suggest me.
$1 cases on eBay is good enough to protect from scratches IMO.

Will I be able to get a reasonably priced apple laptop with merom, 802.11n, blueray burner, possibly HD, and leopard (or whatever 10.6 is called) in late 2007 or early 2008?
Well you know you'll get merom and leopard by that timeframe. Personally, I believe you'll get 802.11n and a blueray option as well - and with a blueray option should come HD as well.

Conversely, I could see them offering different quality versions for those broadbandless people similar to different quality versions of trailers, so who knows. I'm just anxious to see what they'll be offering on the 12th. It's very exciting.
I agree on the excitement, and the potential for different quality options*, but I don't think even their current video offerings are attractive to anyone without broadband, since the typical 30 minute show would take ~4 hours to download. A 2 hour movie would then still take 16 hours to download on dial-up. I don't think so.
By comparison with a 3 Mbps pipe you should be able to download the same show in ~4 minutes or 16 minutes for the movie.
EDIT: * I wish they'd give us a lossless option for iTMS audio too.

Not getting any of these at all.
I suspect that a particular application causes these crashes as this behavior only exists on one account of my machine. However, I have not been able to pin down the culprit...
Does anyone know what the following error message in the crash report may indicate?
xpchelper registration failed for sandbox candidate.: _xpc_connection_send_serializer_to_port() returns NULL

I hope so, and I also hope they don't skimp out on the Mini.
According to the Buyer's Guide, it's been over 300 days since the Mini was updated and the average is 248 days. So they're a tad behind.
I don't think Apple have any excuses on this one. It's been far too long.

there are what, about four movies on BluRay? how much do each cost? If there are barely any players, what's the point of blank media? BTW, don't tell me about storage. if you want storage, get a portable 30 GB HD.I'm not saying I don't think BluRay won't be really cool. it'll just be more reasonable come MWSF time.
I think there are about 20-30 titles available for both BluRay and HDDVD, though I know I only saw a small selection at Best Buy. They were all priced around $24.99. Perfectly reasonsable and comparable to how the launch of standard DVDs went, though I think those had a higher launch price. I rememver movies debuting at $30 bucks. Players started around $700 i think.

EDIT: I forgot to post this earlier: a GM spokesman has denied (http://www.vindy.com/news/2011/feb/22/diesel-cruze-report-refuted/) that the North American Cruze diesel has gotten the green light for production. He seems to imply that GM is waiting to gauge reactions to the existing Cruze lineup before making a decision on a diesel option. So, no new information really. It's obviously a product under consideration, but it seems unlikely we'd see it in showrooms till late next year at the earliest.
Talking about stolen design.... Hyundai i30... BMW 1 series... look familiar? I swear they have the exact same back panel! BMW had the look first then all of a sudden hyundai made a car that looks like a 1 series from a distance until u get to see the badge
There is a certain similarity, but I chalk that up mostly to the family resemblance between almost all 5-door hatchbacks, especially in the rear end. Besides, the i30 is a FF economy car while the 1 Series is a FR luxury sport hatch, and many other car manufacturers have been aping BMW's style for decades.
