Well, after 30 years of building my own computers I have entered the dark side and purchased a mac pro with dual 2.8ghz Quad Core's. I wrote a long winded 1st post and it refused to post, all I had written was gone and now I don't have the energy to re-create it. Don't laugh, I was using my MacBook Air and Leopard for that post. Now I'm using my HDX. Anyway, the machine should be here by 3pm CST and I look forward to using both Vista and Leopard like I do on my MacBook Air. I ordered 4 gigs of Apple approved memory as well, so we'll see how it does with that installed next week. After that I'm going to look for a RAID card so I can use my Raptor's.
