Well, if I buy a refurbished iMac Intel from Apple, it comes with 512MB of RAM and I would update to 1.5GB as I wouldn't want to have a perfectly good RAM stick laying around. If I bought new from Apple, I'd get the 1x1GB stick so that I could upgrade to 2GB. The thing I liked about the G5 was that it could go up to 2.5GB. Does this change any minds or spark any new opinions?
