Unsure what price it will be there in the US but I really really love my ipaq 4150. Its got wireless, BT, changable battery and its super slim and light. I highly recommend it - and for me to actually like a product it must be good! Of course they'll be other ipaqs that will do the job just as well for less money I'm sure.

But it doesn't take CF cards and I have no idea about the landscape thingy, sorry.
