ive got an HP iPAQ RX3715 cost me £160 on ebay refurbished by HP cant remember the cost new.
its got a VERY good screen, built in 1.2mp cammera for pics and videos, Wi-Fi, Bluetooth, Infra-red and even comes with VERY nice software that lets you set it up as a remote control for anything and has different rooms so if im in the living room it lists all the stuff i can do (cable box, TV, DVD player, VCR) and even lets you dim your room lights if your lights support it.
