I have to agree with whoever said that, without HTC, WP7 would be even less known and hated on due to the problems with 2/3 of the other OEMs who have phones out, namely Samsung and Dell. Both have many problem units out that still haven't been fixed yet (I don't think Dell's fix is out yet, is it?). And how many devices has each of the others made? 2 for LG (1 of which isn't available in the US), 2 for Samsung (1 of which isn't available in the US), and 1 for Dell. That's it. HTC has at least one on each major US carrier and a total of 4 (5 if you count the HD7s as it's own) and there's the Mozart, which isn't available in the US.
That said, I also agree that, seemingly thanks to Android, HTC is crapping out devices rather than focusing on greater designs. HD2 -> HD7 is the perfect example and so disappointing. There was hardly any (if any) improvement to the next generation. If anything, this rumored Eternity should have been the real HD7 (though they'd seriously need to increase the resolution to at least qHD with that big of a screen).
I don't think it's all bad though. The TP2 -> 7pro/Arrive has improvements on hardware and design. For example, using the metal for the battery cover, making the number row easier to press on the physical keyboard, and making the speaker easier to hear when the screen is fully tilted on a hard surface. Yeah, it has it's lackings, like the use of plastic trim around the screen instead of more metal, I don't think it has Gorilla Glass, I'm still not sure if it uses SLCD or not (though the screen doesn't seem bad either way), and the screen is still 3.6" instead of 4+", but I'm still enjoying the hardware improvements over the TP2.
Anyway, meanwhile, there're no rumors about any new Samsung or LG Windows Phones. Many of you guys may not like the quality of HTC, but they are at least putting out phones for people to choose on WP7, instead of almost exclusively focusing on Android. So, yeah, I can understand complaining about HTC, but there's no reason to single them out as if the other OEMs are doing any better.
