Let the hive mind of Engadget get that for you.
"I'm in the market for a new phone and money isn't a limitation. I'm also not partial to any particular US carrier, but here are some of the features I'd like to have: WiFi, GPS, good coverage in lots of places, push Gmail (a must!), physical keyboard (a must!), a touchscreen, decent battery life and a relatively slim body. And please, nothing that has a fruit logo on it. No offense to the fruit fans, though. Thanks!"
If its just the same PalmOS, then it might be fine to stick with Verizon but I'm thinking that craptastic company will screw with the OS and lock down all the cool stuff. I'm going to Sprint and the Centro in a couple of months. Nothing like firing up a game of Doom or Quake while I'm waiting for the clothes to dry!

As much as Verizon execs deserve to burn in hell for all eternity for the crippling they do on phones, they generally leave the Palm ones alone. I think Sprint's phones come with a few extra apps in ROM, but some people call that bloat. Depends on your perspective, I guess. But unless they've changed policy with this model, you should find the 755p just as open as any other Palm.
They'll cripple Bluetooth as usual.
