new iMacs: the machine I was waiting for

Quick reaction: I'm an iMac guy. I know I should be Mac Pro given what I do but I've always been a sucker for design and the combo of 24in iMac with an added 20in screen for less than the price of a Mac Pro well... it's hard to resist. Add ultra-silent operation to the mix and I'm there. But my machine has been showing its age for a year now and I've been itching for new gear. Well folks, change is upon us!

Apple introduced new iMacs today and the changes are pretty spectacular. They've dropped the 24 inch model for a new 27 inch display at 2560-by-1440 resolution. And at last: quad-core has landed! I had skipped the last round of updates because I was holding out for this. So color me happy.

The specs for my new iMac will be the following:
2.66GHz Quad-Core Intel Core i5
8GB 1066MHz DDR3 SDRAM - 4x2GB
1TB Serial ATA Drive
ATI Radeon HD 4850 512MB

That's right: 8GB of RAM! It comes stock with 4. I might also get the 2.8GHz Quad-Core Intel Core i7 for $200.00 more. If I do the grand total will be $2500 CA which is less than what I paid for my Core2Duo 2.1 machine with 2gb of RAM.

I've been looking into the differences between i5 and i7 processors and the biggest one is support for hyper-threading which I believe allows for 8 virtual cores - which means running more tasks in a more efficient manner. Does this allow for real-world performance boosts? Probably depends on the application.
Aperture 3 could use that quite well dontcha think? C'mon Apple, might as well take all my money...

Other features of interest:
- In-plane switching (IPS) which apparently increases the viewing angle while minimizing color-shift.
- The new Magic Mouse  looks pretty sweet. Just in time too: my Mighty Mouse finally gave up three weeks ago.

The biggest unknown for me is the glossy LED display and color accuracy. I've never had color problems with my current machine (matte screen) and the spyder3pro. I've heard of problems with screen brightness on the previous generation LCD displays but I'll need to look into this. Apple states that "LED backlighting also gives you greater control over screen brightness. So you can finely tune the iMac display to suit the ambient light in even the dimmest room." It's nice to hear. Now it needs to also be true for day-to-day operation. I've bookmarked ColorEyes Display Pro just in case.
