Exactly what iMac do you have? They've been shipping standard with 1 GB or more for a long time. But if you need to run something on the Windows side and Fusion isn't helping, don't forget Boot Camp.
You really need to scrub your hd once a year or so if you use a pc, don't know about the mac yet.
I had a six-month scrubbing cycle on my PCs. I'm going two years with no scrubbing on the Mac. I did an in-place upgrade from 10.4 to 10.5 with no problems (I always wiped Windows before an upgrade).
They change their website B4 they ship and call me, and I end up with the 24" monitor and 650 gb, 4 gb RAM at a slightly lower price. That was great of them as I'd have never known the difference. Think the price ended up at $1600 something, that would be on an old cc statement, not going there tonight.
Darn cat was on the imac keyboard, booted up the imac went bonkers. If I'm on the computer, he's on the imac side of the table. If I'm in another room, he follows me. Says Mac OS X, Version 10.5.6 2.66 GHz Intel Core 2 Duo, Memory 4 GB 1067 MHz DDR 3 more info, enough of that. There are some updates I need to run, don't know how to start those yet.
Maybe the imac has builtin bootcamp. I don't know at this point. Too many people in so many months have told me more than I can digest right now. I might as well use Fusion since I bought it, but I still might have to designate so many gb for that, won't know until I get into it, read what came in the box and not ready to deal with it.
