This is a terrific PDA.
I was going to buy a Treo phone/pda until I realized that my need for internet access didn't warrant the extra monthly expense(Treo's, as far as I know, don't have built-in WiFi).
If you're like me and you're attracted to the idea of both simple operation and, of course, "free," wireless internet acccess, this baby's the one for you.
Seriously, if you don't NEED a full-size laptop, this wireless (read: free internet) device can be used to quickly check e-mails, do google searches,mapquests, etc. in addition to doing everything else a PDA does to help organize a busy life. When I'm on the road, I usually have free wireless in my hotel or can find it fairly easily (Panera Bread's one popular option) and some (but not all) major hotel chains and airports. Plus I can load photos, videos and music for my personal enjoyment.
Again, it's a must have if you don't quite need a laptop. In fact, even if you do use a laptop, the Palm TX can still be a handy tool. For example, It doesn't take forever to "boot up" like a computer so it's ready - and you're online - in seconds. Kudos to Palm - this one really hits a homerun and I truly enjoy using it everyday!
