So yesterday we bought this. We went with the 24" display and upgraded the memory to 2GB. Otherwise, we went with the standard iMac, which in and of itself is pretty cool.
Setup took all of about, oh, three minutes. We had to connect a mouse and keyboard to the back of the computer, and plug the Roadrunner cable into a USB port, but the overall experience basically entailed taking it out of the box and plugging it in the wall.
I've never seen such a sleek and cable-free design. It's very cool. And that 24" display is truly dazzling.
Then it took my picture. I set up my account, was momentarily puzzled by an onscreen notification to smile, and then was surprised by the fact that my grizzled visage actually appeared on the screen. I'm not sure if I like this, but there you go. With an internal microphone and an internal camera, I am apparently ready to teleconference myself and podcast myself to the world. Look out.
We decided not to go the Parallels route (at least for the time being). We did buy the Mac version of Office, and old docs created with MS Word opened without a hitch. And I bought Age of Empires III. If I cannot literally take over the world, I can at least now virtually do so.
