Of course, as a Power User, this leaves me... I dunno, miffed? Annoyed? Agitated?
I'm like 90% sure I'm going to want this thing if only for the fact that it's an eBook reader plus other stuff, but I don't see it being able to replace my laptop for programming when I'm away from home. That's not Apple's fault for introducing something that doesn't completely subsume the personal computing experience, but it leaves me somewhat anxious that now I'm going to be carrying around an iPhone and a MacBook AND an MacLet (iSlate, iTablet, TaBook, iWhatwever) when I go on a trip or something.
That's just too much gear! I at least hope there's some sort of unified power solution between MacBooks or iPods and this thing.
