I'm using the lowly Palm Zire right now, but I plan on upgrading to whatever is new and cool in a year when I hit clinic. The Zire does all I need it to do at the moment...tell me when I have things due and coming up, and it lists the contacts I need for these first two years. When I need Micromedex et al, I'll get the latest and greatest. I think Palm has a better OS, but since I'm using Windows at home, it'd only be that much easier to hotsync with a PocketPC. It all comes down to personal preference in the end.
Might I also add, I recommend a glock for those of you in urban areas. 😀 J/P
