The iPad keyboard case I ordered arrived yesterday, it adds a bit of "heft" but that doesn't really bother me, in fact I quite appreciate it.
It's got one good feature I wasn't aware of, when you put the iPad in the typing position the case touches a magnetic strip just above the keyboard which automatically turns it on.
So, now I'm going to try to work it into my routine more and not just as a large iPhone.
I'm not going to get into the whole "laptop replacement" and "can you get real work done" debates - they're pointless. Besides, I've been getting shit done on a phone for years - never mind a tablet!
