In my POV, don't buy it. My ex boss had one (cingular) and thing was droping calls right and left. He had to go thru 5 of them before he received one that was working. One of our customer had one also (Verizon), and he returned it becuase he was loosing all his appointments from time to time.
I personaly have the Pocket PC (Verizon), windows based.
On the function side, I like it better than the Treo, especially on the appointments/callendar. I can set way more options on my appointment and contact lists than the treo.
I also have Word, and Excell. Excell is a great tool because I have all my airplanes Weight&Ballance sheets on it, and can do it "on the spot in no time".
Phone also has the WMP for my MP3s, with full screen video capability. And handwriting recognition. I personaly never used the sliding keyboard.
As far as browsing the web, you have 3 modes of display, the one I use can put the format of the page to the screen and make pages readable and easy to navigate.
The drawback of this Pocket PC is his battery life. It's a power guzzler. Don't expect more than 3h of continous talk. So I end up driving around on a car charger. The remedy is to buy a big battery like a 3k+ ma that will bring you 8h of straight talk time. The Treo, having less gadgets, will give u 4h of staright talk time.
My version of the pocket PC doesn't have a hard drive, which means that when u run out of battery for too long, your datas are errased! I go around that by saving all my datas on my 2G SD cards, just in case.
I also have an anoying bug where the phone line locks up between calls, like once / twice a week, and I have to reset the line, which is just a click of a button.
It's my understanding that the NEW Pocket PC has a hard drive and that the bugs and inconvenience of mine have been worked out. Plus it's a bit smaller and easy to carry around.
