Is there a Blackberry or Palm Treo device that manages email?

You can do the same with a windows mobile device. My Motorola Q can do the same. My data plan is 30 dollars a month with my voice plan. Its a little cheaper than a Blackberry data-plann. My data-plan also has unlimited internet usage as well. The Motorola Q is thinner and doesnt weigh as much as a Blackberry. It might be worth looking into. My serice is with Verizon. Good luck
