Why I think HTC markets many models...
I think various phone makers to this because some carriers are wantonly greedy or selfish in demanding that a certain curvature or shape on one side or speaker grille treatment be made. Some want certain control chips inside. Some want certain stock, consumer-right-to-have features disabled or stripped or just crippled.
Just look at the Samsung Note. Sprint ALMOST had it, but AT&T got it instead. I don't know whether one carrier paid more or another made this-time-it's-tooooo-unreasonable demands. If Sprint got the Note I'd have dumped my EVO 3G IMMEDIATELY. But, I'm not going over to AT&T.
Even still, what annoys the hell out of me right now about my EVO 3G:
-- HTC or Sprint or Google keep sending me a header message that a minor convenience and security fix is waiting. INT WTF? Why ask me? All kinds of other imposed, mandatory, forced reboot slipstream code comes to my phone. WTF is it that I have to approve personally for THIS one? What, is it some federally-mandated backdoor that strangely requires my assent to it lest a case be toss out if I'm under investigation? Sheesh ! FORCE the fecking upgrade and be done with it.
-- The other thing annoying me is that the keyboard is laggy, and sticks. It is in-FUCKING-FURIATING to be speed typing along, only to find 15 out of 60 letters are dropped or tripled, only to suffer a further indignity of the back arrow key not working, then forward doesn't work, and the delete key won't either. I can thumb-insert the cursor and then inconsistently make new text, but not edit or delete the trailing, undesired text. Worse, long-pressing to get "Select Word" and selecting for cut the stuff I want to be gone makes ALL the text vanish.
Sense UI is probably fracking up sales for HTC models. I am itching intensely for a HUGE Note-like model. Either on Sprint, or one I can get elsewhere.
But, I, too, agree that HTC needs to cut back on the plethora, same-month-release-of-multiple-models. Definitely more than ONE model every two years, but fewer than 10 per year.
