Something as light to the touch as the iPhone or iPad I simply 10-finger type by putting it on my lap...
I'm not. Right now it's on my lap...
Got it...that's what I assumed (I was trying to see if I was missing some other physical way to hold these things other than the obivious...)
For
me personally, I want to be able to type comfortably while holding the tablet like a book. This essentially means thumbing. I don't expect that one can thumb faster then "pseudo touch" typing...but I don't expect to be as productive on a tablet as on a lap-top either. I do expect to be more productive on a tablet than on a smart-phone of course.
In other words, for your (Mize's) use...you say "If I'm walking about I'll use a smartphone." For me, I say "if I'm going to be putting it in my lap, I'll use a lap-top."
I want to use my tablet while walking about, or while sitting down or in bed holding it like a book. The tablet would be used for media consumption, internet and e-reading, email (reading and composing) and message board posting.
So for me, a 7 inch form factor is what I'm gravitating toward. Possibly a 10" if there is a decent thumbing solution (like that Android app). Though 10" is a bit more limiting in terms of portability.
So I'm awating the Playbook, and I also believe over the next few months some Honeycomb tablets in a 7" form factor are supposed to emerge. (Acer? Asus?).
Ultimately, for me I think that I'd really want a 10" tablet to be a notebook relacement...which really means that it would have to be windows based.
