I got a qubits one off amazon and its good enough for me.
semi hard plastic mould that protects the vitals and doesn't add too much to the bulk. I needed something to stop it slipping out of my hands so easily and sliding along the passenger seat of the car...
RE: Battery I get nothing like as good as you guys. Granted I use it quite frequently but I'm lucky if it lasts a full day without seeing a plug socket late evening. Last go was around 1hr 40 mins of screen time with ~ 40% brightness, WiFi on, some light gaming (Scramble, and Words etc) some facebook, some BBC news, texting, etc and it got to around 15% battery before I plugged it in at around 8pm.
Maybe I need to reduce my brightness somewhat.....
Can't wait for the HTC update
