It is easy to remove it from stem or put to another bike; during cycling I can take out phone and talk; it is waterproof; I can operate on touch screen while riding bike - change screen...
The only thing is... it is a little too big for may PDA phone.. I am searching for smaller bag :-)
My cell phone is a HTC Touch Cruise. I saw in otterbox's site that otterbox model 2600 can be used from cell phone like mine. Right? Suggestions or other case?
I second otterbox, I use the otterbox 2600 for my htc tytn II, it's little big but very acceptable. I zip tie it on my stem.
you have also the boxit 5.0 : www.boxit.net , if your phone is small enough (for instance my htc tytn II can enter inside the boxit 5.0 small lid, but it's very tight and it's a bit of struggle to get it out afterwards)
