Ok, i was very disappointed with the Mac Mini refresh. New units are just too expensive for what they are. Heck the refurbished are as well. Anyway, I am considering the refurb Core Duo Mini. Few questions: 1) Will Intel GMA 950 handle hi-def XVID decoding? 2) Does upgrading the ram to 2gb myself void the warranty? 3) Will running MS Windows in VMWare work well on this model Mini? Thanks!
