HTC Advantage x7500 pocket PC phone (when I got the iPhone), which could get net access (a mobile version) but couldn't sync my other devices.
The solution I found was the
OQO model 02 UMPC. It is a super small tablet PC that is small enough to carry in your pocket. It even has a slide away keyboard with integrated track stick which makes it an amazingly useful computer. Its not a terribly powerful computer, but it sure does work great for me. I can easily sync my devices, surf the internet from the couch, and it easily goes to work with me in my lab coat pocket. The pharmacy I work for does have computers with internet and Microsoft office, but no color printer and no Adobe Acrobat Pro so when I have the need, I just grab my OQO and plug it into a $25 HP printer, or can generate a pdf. The only things I feel it is lacking are an extra USB port (there is only 1 port) and a SD card slot; however, it does have a HDMI port(go figure). With WiFi and bluetooth, I can use a wireless keyboard and mouse, then just dock it to a larger monitor if I have the need for a bigger screen.
