Juz read the specs for mac mini, its packaged with a mini DVI to DVI adaptor, but no KB & mouse. If u buy original mac KB & mouse its a hell of a lot of money, so juz buy "3rd party ones" like microsoft or logitech brand.
Cost aside, i really like how apple sell their macs. U dun juz buy a computer & fig out the rest urself, the website is full of basics & beginners' advice to help users new or old. Also the software package is attractive, u get the OS which is fully useable w/o much apps for basic things like iphoto, movies, disc burning app, xcode for programming, etc. IT guys can use the unix kernel to link things around. Think not bad.
My XP is already 3yrs old & i'm now contemplating to go win7 or Snow leopard with my next change. Hmm... My biggest concern wud be online transactions, some use active X for certain features, so compatibility wise, i'm not so sure.
