No, I do definitely understand that... what's your rationale for using Vista?
It works like this - my Dad has on old PC, and is slow to change old computing habits. He hasn't warmed to some of the G4s I've got around. But as soon as Vista is mentioned on the news, he wants to buy a new PC with Vista.
He always complains about mess in his computer room though. We have a big box PC, from 1998, with a big CRT screen, loads of wires, etc.
Now, I've really fallen for the Macs, and I would love to just give him the all in one iMac with wireless keyboard and mouse....bye-bye mess...and look(!)...it'll still run Vista, and all your PC apps.^_^.
Meanwhile, my Mum has been learning to use a computer, and finds the Mac OS really easy. She has her own login in Tiger.
Strictly speaking, I could probably get away with only having Office on Vista for my Dad to use, and just Mail and Firefox on OSX for my Mum to use.
But I do love the idea of weening my Dad over from Windows to OSX...to show a comparison of the same apps in each OS...but perhaps I should accept you can't teach an old dog new tricks?
Is it for games, specific applications, etc? Is Parallels an option that would eliminate the need for duplicating all your apps on both sides of the computer?
I don't know what Parallels is at this point in time, but I have seen it mentioned in the subject headings of some of the other posts, so I will go and look it up, and get back to you.
