I was looking at one. The look pretty cool and have lots of options. Check out the link. http://web.palmone.com/products/smar...50/index.jhtml
They are pretty cool...I used one for a while....upside...good browser, nice screen and graphics...bigger/better display then older Blackberry types...
Down side, screen gets washed out in the sun (hard to see), pocket pc wi/fi access for staying connected is less stable then current blackberry (rim) methodology. Not fun to use as a primary phone...wide/fat...need to hit key to bring up touch screen then use touch screen for dialing. You might want to try the new Blackberry 7100G (cingular)...narrower/thinner more phone like with graphics like the treo...still gets washed out thought...I have been using the 7100 for a couple weeks now.
