I think it's neat, but certain things conspire against me getting one:
1. No expansion ports. I'd love to be able to take this thing on the road to do diagnostics on some of the equipment I do work on, but w/o a way to connect to a serial interface, it's useless to me.
2. Single-tasking OS. Come on! This might have been acceptable 10 years ago, but now it's just sad!
I'm sure that in time Apple will change their approach, but I'm not gonna go for this first gen product.
