I just traded my Treo for a Mogul. I love this phone. Biggest difference, it's Window's mobile OS as oppsed to the Palm OS. I love that it has the handwriting recognition. I use it for both "texting" and my emails. The PDA parts work great, and so does the phone. The 2 mega pixel camera, with flash, is handy too. I don't miss the Treo at all. If I have any worries at all, it is with the slide for the keyboard. I just wonder how long that will last.
