You'll find the OSX side of things should have a higher gamma setting than Windows (unless the Bootcamp drivers fix that). It makes all of the colours look crisper and more vivid while remaining a neutral temperature. The IPS Panels on the Pros are awesome. The Airs not so much, but still better than most.
My main frustration is that the Pro 13" STILL only sports a 1280x800 screen. I mean, 1440x900 I could understand. Oh well. Not like I'll be upgrading for a long time, anyway. Need to save my moneys. :D
One funny thing is most browsers also scales memory usage with the total amount of system RAM. IE will also stop splitting processes after a set number of tabs if it's a bit too many - depends on the system resources.
Haha, I wouldn't know how much Safari or Chrome use on iOS, as you don't get any sort of Status Monitor. There's a hidden force-quit system, but that's it.
On the desktop side of things, I've used Chrome for 3 days without closing any tabs to see how much memory it uses. With about 40 tabs open, it was using 3.5GB memory on my Macbook. The with everything else open, I was using 6.2GB RAM. Who says more than 4GB is a waste?
