Mobile phones and devices are my favorite technology.
I remember my first Pocket PC (I think it was a Viewsonic). I moved to a Dell Axim, which I loved, and it was the Axim that first got me hooked into web forums (Aximsite). After the Dell Axim I had the HP Ipaq, and soon after that I started wanting a device that would combine phone and pda together.
My favorite phone of all time is still the old Nokia 6230. That was a stellar phone for it's time, and it was the first unlocked phone that I purchased and the first sense of freedom from the US carriers lock down of phones.
