I'm surprised everyone is saying 4.3" is too large. I think smart phones are headed to the larger direction, Dell's android tablet with phone capabilities seemed like one of the first steps. (I forget its exact screen specs, but its way larger than an HD2/Evo)
But for me, the HD2 is the perfect phone, I just can't be tied down to WinMo any longer, it simply frustrates me. I kept waiting for them to release a version with android, and while the Desire looks fine (though I think the N1 may be better if only for guaranteed updates), I still miss that larger screen.
I guess its a preference, but the EVO is my perfect phone, just with the wrong radio bands
But is 4.3 really too large? I still find web browsing on smart phones limited with the screens, i feel like it requires a lot of scrolling. And if you're saying 4.3 phones cant fit in skinny jeans, get a purse to go with you jeans and put them in there.
