Well i finally took the plunge and bought myself a Mac Mini...
So far, i havent been able to fault it, it runs incredibly fast for its size and spec, (ive even been playing games on it, lol) tons of eye candy from aqua too if thats your thing and it looks so damn good sitting on my shelf lol
You can even get a bash terminal so you can do things the *nix way if you wish to and being built on BSD, ive got a good foundation from using FreeBSD 5.x
The only gripe i have is the keyboard... its like some USA/UK evil hybrid with the @ keys in the wrong place, and keys missing like the # key is actually alt + 2 (i had to google to find that out). There is no home/end buttons either which is a bitch (unless im missing something).
(excuse the poor picture, was taken with my phone and the projector screen tends to screw up photos)
