By no means am I a frugal person at all, but honestly, this phone/PDA thing is out of control. Right now it is looking like this device will go for around $750 to $800. Don't get me wrong, this is definitely a neat device, but definitely not worth dropping that much dough on.
Probably the nicest features I see is a full QWERTY keyboard integrated. Along with that, this electronic powerhouse has a 240 x 320 TFT touch screen, supports MMC/SDIO memory, integrated 64MB ram, 128MB ROM, a TI OMAP 850 processor, 1.3 megapixel camera, Bluetooth, EDGE, WiFi and is all powered by Microsoft Pocket PC 2005. The guys over at Kemplar have this phone/PDA shipping for $745.
