HP h6315 / h6310 / h6320 / h6325

As it is, I already have an older 3870 that I have the Sierra Wireless AirCard 750 with a T-Mo data plan (unlimited for $30/mo is better than anyone else by a long shot) and I use that for data for now. Since I cannot get the HP to be a good phone, I'll upgrade both my phone AND my PDA to a newer (smaller) phone and the new HP hx4705. If I'm going to have a new PDA, might as well get one that is the TOPS. The hx has faster proc, more memory, and a larger screen (480x640--sound familiar?), plus all the things that make the h6315 interesting (BT, WLAN)--just no phone. Though I am seriously looking now at the AudioVox SMT5600 as a good alternative to the Nokia 7610. We shall see.
