They had them setup in the Tulsa Woodland Hills store, both 20" versions.
I really like the new keyboard, travel is short, crisp and tight. I really like it, in fact I wonder how well it would work as a PC keyboard.
I decided to wait until more information comes out, and I'd really like Leopard in the same box at the same time, so I'm waiting for October. But the look and feel of the new iMac is very nice. Seeing them side-by-side the old ones makes the old ones look so... old.
And many of the applications in iLife seem to be taking on the Black Glass appearance that the iPhone and other Leopard applications are using, so I'm starting to think we'll see a lot of Black Glass in the final version of Leopard.
