i made a mock up of the streak.. printed off screenshot stuck to 3 pieces of cut out corrigated cardboard to see how the size was..
it's thin.. very thin.. and big.. very big.. even compared to big things like the hd2
it's also easily pocketable if u only wear big baggy jeans.. but in a suit type thing.. i think it'll be a no go..
As far as onscreen keyboards.. you do get used to them.. I'm ok on my 5530, and that's pretty tiny.
My biggest problem with it is still android. i don't see why manufacturers insist on all this customisation. surely a stock implementation that can be updated as soon as a new version is available is by far the prefered option?
