Actually, it's not mine. I got it for my wife who recently got a job that involves some travel. It's our first cell phone (yes, we've made a major leap into the 90s ), and I couldn't be happier. I've seen PDA/cell phone devices before, but nothing that has an "always on" connection like the Sidekick. I mean, what's the point of having a mobile email device if you aren't notified when an email arrives, and you still have to invoke a dialup session to fetch it? Also, I've never been attracted to the notion of using a PDA for fear of losing it, but everything you enter into the sidekick is mirrored on the T-Mobile server. If you lose your phone, your replacement will have all the same information on it. The mirrored PDA information is also accessible from any web-connected computer. But the coolest thing is that I (I mean my wife) can surf the web from anywhere. I'm typing this on the Sidekick as I'm waiting for an oil change, which is way cooler than reading old car magazines. Does anybody else have one of these things?
