The HTC Puccini actually turned out to be the HTC Jetstream, a Honeycomb tablet for AT&T. Announced on September 1st, HTC will make the tablet available for $700 on-contract September 4th. It's a 10/1 inch device and looks to be a monster of a device, specswise.
Inside we have a dual-core Qualcomm 1.5GHz processor, 1GB of RAM and more. One unique function the Jetstream has is its HTC Scribe support, similar to what is found on the Flyer. The tablet will be compatible with HTC's digitized stylus (the Scribe Pen) that'll be able to tell the difference between the pen and your finger.
