There are a lot of so called smartphones out on the market and without doubt this is in the top two. The pro to this particular model s really size. Size matters. I have used both this and the Treo 600 (which is typically mentioned when you talk about this phone) The beauty of the Samsung is the flip and graffiti funtions. The Treo has neither. But the Treo does have a nice navigation button and a qwerty thumbboard(a little small for my tastes), a camera, and expansion slot. Which can be used to hold additional data and applications. While these might sound like a lot I dont have much use for many of them. Especially the camera. Its terrible. I beleve that both devices serve their puposes very well. But if you are looking for a PDA/smartphone with the compact size and functionality of a normal cellphone you might want the Samsung. P.S. I believe that Samsung will be releasing a new version of this phone later this year that will be even better. Might be worth the wait.
