My first Windows Mobile device was an HP iPAQ 1945, which had WM2003 on it. It cost me over $300, which was very pricey for me as I was just starting college, but I certainly got my money out of it (owned it for 13 years before I finally decided to e-recycle it). It was so cool. I used it to keep track of appointments and to-dos, listen to music, watch videos, take notes, record notes. Later on, I even got a Wi-Fi 802.11b SDIO card for it to browse the Internet. I know that now, all that stuff comes basic on even the cheapest budget phone, but at the time, having all that stuff in one tiny little device was amazing. The Palm m130 that I owned before it couldn't do half as much as my iPAQ.
