My new iMac arrived just minutes ago. After so long in the Windows world, I can't believe how small the packaging was. When I saw the Fedex guy walk up the path, I was telling myself it couldn't be the iMac ... what could my wife have ordered? It's smaller than the box my 17" Dell LCD monitor came in.
Set up was a breeze - I'm typing this on it now. The screen is nice - better colors than the Dell LCD I have to say. It's so silent too - I've just copied my iTunes library (not imported yet) and the only sound was the external USB drive spinning away.
Yesterday I went to CompUSA and played around with a G5 for a while to get a feel for the differences. There isn't much to say with normal use, but when I opened all the apps present in the dock at the same time, the G5 churned away for 5 minutes and gave me lots of beachballs (CPU pegged 100%). When I did it to the new iMac neither CPU went over 45%, no beachballs. Of course, I have 2GB RAM so that helped - still it's nice to know it take what I throw at it.
