I like HTC devices, indeed all my smartphones tend to be HTC.
Yeah, it's a common case of YMMV. Sensation looks really great on paper, and pretty good in reviews, but in practice it's just not a good phone. I can understand some
bugs in the OS and the attendant software, but the issues I've had really turned me off. At one point it stopped playing text message notification sound and only a hard reset (i.e., wipe all user data) restored it.
USB connection to the 'puter hardly ever works - you connect it and nothing happens, regardless of settings. It takes about two minutes (!) to establish connection, but often it never connects. When it does connect, it resets (crashes) on disconnect. So forget about using it as your primary music player, transferring files is just too annoying.
I live in a busy city, where coverage is perfect. Put the phone on the table, get four bars (max). Pick it up, display drops to 1 (one) bar. Go somewhere less populated, and I have to reach for my old Nokia to make a call.
The Sensation is the first phone I've ever had that drops calls. When it does connect, sound quality is poor, and too often I can only hear every second word that's spoken on the other end.
It's good for browsing the net (but don't hold it in your hand when you do!), but it's a really poor phone. Easily the worst I've ever had.
