Quote from the review at Howard Chui:
“Virtually all usability issues users had with the P800 have been addressed with the P900. Unfortunately there aren’t really any huge upgrades with the P900. I was especially disappointed that there is no wifi option on the P900 and that the cpu feels like the same speed as that of the P800.
Still as far as PDA/phone combos go, the P900 is an excellent choice. It’s a good phone, a good PDA, it’s easy to use and has a high level of integration between the phone and PDA.”
