First of all, none of you (as far as I know) are personal financial advisers, so stop telling the man what to spend his money on! If he wanted that kind of advice, he came to the wrong place, he wants to know about track bikes. Also, fyi, PC > Mac. Macs are slow, over priced garbage. And I have had both, Mac and PC, but that's all personal opinion. No computer lasts more than 3-4 years, so might as well get a cheap, powerful PC.

Anyways, as far as bikes go,

GET THE CONCEPT. There is no other bike like it and you will regret not having one. It's one of a kind, beautiful bike. If you are a fan, you should just go for it. If you can find one, get a Cannondale Track. Cinelli bike is sweet also. I would go w/ one of those 3, personally.
