hmmm, well maybe in another two years WEB OS might be as advanced as WP7 is now? I loved my Palm Pre when it was supported, but recalling too, that I had to patch it, doctor it and uberize it and STILL had to put up with "too many cards", hang ups, slow loading, freezing and rebooting, not to mention toting a spare battery, having three touchstones handy - at work, home and in the jeep - and STILL the battery life was deplorable - no, I think that WP 7 is a much better platform - no frezzes, no reboots, phenomenal memory room, free cloud storage and all - straight out of the box - without me having to do anything except turn it on!
Good luck to the WEB OS community, hope there are some developers willing and able to fan the embers!
