I had always thought that I would never own a Mac. Well that is still partly true, but now I do have an old Mac that I bought for $260. When I was in India, I did think that, given the price factor of a new Mac, I would never buy a Mac. But recently I moved over to Oz and though that investing about 3K on MacBook Air would be good idea. But then I dropped the idea completely as the only reason for which I wanted to get it (the Nvidia mobile 9600 graphics processor) was not really good: it only had 128MB VRAM. That meant I would not really be able to do CUDA programming on it.
As far as laptop was concerned, my Mi Leap-L (now dual booted with Vista and Ubuntu 8.10) are great for my work and for communication back home. But I still wanted to try Mac. And Lol, the CS department came out with an old Mac sale :) This is iBookG4, 12.1" (not the new Intel once), but pretty cool .. Am testing it out, so may post some more info. at a later time :)
