The Palm OS version is much better, but I did somewhat like using this version as well. I'm giving this phone 4 stars because of the network it is running on, but the phone itself is not the best. Palm ALWAYS comes out with a phone with limited memory, then comes out with a minor update later with a little bit more RAM. There is far cheaper phones with more memory out there, which is sad, seeing as Treo's are very high priced. Palm came out with the Treo 600, then came out with the Treo 650 with a better screen and a but more memory. Now there is talk of a Treo 750, with the same type of upgrades. This has caused me to totally give up on Treo's. For Palm to milk us customer over and over again, with small upgrades, shows no respect. Palm also outsources their customer care, so good luck in getting help. The ONLY perk is Sprint only charges $15 dollars a month for PDA access. Which is far less then the $30, $40, and $50 that T-Mobile, Verizon and Cingular charge for the same type of access.
