Re: "early development hardware"
It's a 'pc' Interesting.
I'm sure the all in one approach is certainly better should it's application be mobile oriented, but a think a connected and/or connectable to a base system (i.e a GP computer) would offer more flexibility.
I do wonder if this is not going to end up being a limiting factor in terms of the devices application (not to mention inclusion/reliance on some sort of 'app store' for s/w installation which would wall it up nicely against all but major corporate licensing).
