I'm the one who voted for "Go scrounge up lots of money and buy a mac!".

I'm long time user of many different linux distros (including "mainstream" like Ubuntu), some other *NIX and BSD based systems, Windows in all it's varieties, Mac OS 8/9 and finally Mac OS X. I prefer Mac OS X - even if i use Windows XP and Vista at home.
If money is not an issue then buy a mac, otherwise give Ubuntu a try. But don't forget your family, especially the kids (if you have any): If they can't play their beloved windows-only-games you will get a little bit trouble.

Just my 2 cents...
