Just the pure fact that the HP Ipaq has Microsoft WIndows mobiles as it's operating system makes this device a piece of crap. I have had several Ipaqs, since the first ones and up to a very recent model. All of them suck, being the operating system's fault. The hardware may be nice, but the os is pure crap.

On the other hand, the Nokia IT having Linux makes it a superb device in terms of expandability, easy to install any applications, easy to develop any apps...in short, open !

Room to improve, of course, but that is why there is a huge worldwide community that works on linux, maemo and hopefully Nokia keeps the I.T. open, even more on each iteration of the device.

On the hardware side, the Nokia's screen size beats the ipaq easily. On the connectivity side, also Nokia wins with a much better WiFi functionality than the crappy Windows mobile network features.

Just my 2 cents.
