I happened to be at HP today and got a chance to see, hold and play with the upcoming iPAQ 6800 (name to be finalised). I hadn't read anything about it so thought I would send you a note.
It is in essence an O2 Atom but with HP firmware and in a silver case with a 6500 style plastic fold back screen guard.
It has:
Windows Mobile 5, tri-band GSM with EDGE, FM radio, 2.0MP camera, Bluetooth (with A2DP & AVRCP support), iRDA, 802.11b & Mini-USB 1.1 port. Memory: FlashROM 128MB, RAM 64MB
This is a real product and from what I hear is due for release in April '06.
