Yesterday I had a chance to check out the new iMacs at CompUSA in Birmingham.
All I have to say is… Impressive!
The boot-up time is indeed stellar at ~25 seconds.
As Macworld recently pointed out, the overall speed boost relative to an iMac G5 is variable, but many tasks in native apps are like lightning. I did not check out any apps running through Rosetta.
Overall, this system is very, very responsive, although I sense we will miss the wide pipeline of AltiVec for some things. Since the iMac supports dual monitors with desktop spanning, I am seriously considering clearing off my desk at the office and replacing my Quicksilver tower with a core duo iMac. That is, once the Rev B’s and enough native software are available. I may do the same at home, but I will wait to see what the performance gap is between the iMac and the upcoming “pro” towers before making that decision.
Seeing the Core Duo units next to the G5 units was striking. There is no obvious difference. I think Apple is trying to give the impression of continuity with this switch.
Bottom line: it looks like a Mac, and it drives like a Mac. And a mighty fine one at that.
