I just returned from a few days of camping with my family for Father's Day and it seems like everyone and their brother was sent a new device from HTC to play with and photos, video, and commentary are appearing all over the place. Sprint announced that the update to the PPC-6700 will be coming in July and will be called the HTC Mogul. The HTC Mogul improves on the PPC-6700 with Windows Mobile 6, higher resolution camera, double the RAM, slimmer form factor, and EV-DO Revision A support.
I am testing out the T-Mobile Wing right now and a couple of weak areas I am finding are the lack of acceptable RAM and a processor that is a bit slow for a full blown Pocket PC. THe HTC Mogul shouldn't have these issues with the plentiful 256 MB ROM/64 MB RAM and a 400 MHz processor. It looks like HTC is standardizing their slide-out keyboards with the Fn and Shift indicator lights and flat large keys. For great reviews and first looks I recommend you check out:
The HTC Mogul will be available in July for US399 with a 2 year contract, US$549 retail. The EV-DO Rev A update is scheduled to come out later this year so you won't have EV-DO Rev A to start off with.
