I already have a PalmV PDA with PalmOS 3.5. I never use it. I practically have absolutely no need for an organizer. Yet, I wanna buy a new one. That geek gene in me (that my mother unsuccessfully tried to kill over the years) what really wants is a "truly mobile PC" that just isn't a laptop. So, for the last few days I was shopping around the Internet for a new PDA (preferably a PocketPC this time) that would fit the kind of thing I am looking for. I was... horrified to find out that what I need isn't... invented yet.
I got a HPQ TC1000. Without keyboart it weighs about 1.3 kg, so I always have it with me. It has plenty of connectivity (WLAN, USB2, Compact Flash, Modem, Network), and it runs for 5 hours. It is also very rugged (I already had a very spectacular bicycle accident with the thing in my backpack).
The new version TC1100 looks almost identical, but it comes with a centrino CPU so it is quite a bit faster than the transmeta CPU of my machine and it runs for 7 hours.
It is much larger than what you wished for, but you get a real PC running windows XP that you can even use for development. At work I just plug in an external 17" TFT and an external keyboard and I got everything I need (Visual Studio and all that).
