Actually, it's quite easy to type a text one-handed on a Note.
There's a one-handed mode that puts a smaller keyboard near to one side.
Good to know, because I almost wondered how you could reach the far left end of an 8 cm-wide phone when your thumb only extends to 6cm.
I think you think it's bigger than it really is. It's only about the width of a 3x5 note card, it's thin, and has a faux leather back that helps with palm grip.
Admittedly, I was always intimidated by its size, and actually repulsed by its use of the Mac-incompatible (¿?) Android OS. But I never paid much attention to its finish, assuming that all Android were cheap plastic.
However, personally I would never put a phone in my back pocket. That's just asking for all sorts of trouble.
When walking that's the finest and least aggressive place I could find for the 3GS, with its rounded back, right next to my bus & metro pass card. Front pockets are already filled with keys, coins, and a somewhat bulky wallet. In winter I do have more pockets, including some large enough for a larger phablet (I assume).
Large means larger battery, plus the Note has some unique hardware to save juice.
Seriously, the reason the Note is so popular is because it packs a lot into a tidy, thin, light space.
Cheers!
So does the iPhone, right? As I remember, the 3GS is actually underclocked by 25% to save juice, but still burns juice like an old-time V8. Sure the Note is thin, and with such a large size and plastic build, is it really sturdy?
