I’ve been playing around the Treo 650 for the past few days, and been quite impressed. In many respects, it's a big move to the all-in-one device I want to carry around. While far from perfect, it has some appealing features: a good Web browser, calendar, contacts, MP3 player and telephone. As a long-time Blackberry user, the Treo's e-mail system is not as good but it seems fine for people who like mobile e-mail but don't see it as a must-have. Before jumping on the Treo bandwagon, I'd have to think about the cost of buying a Treo, the monthly service fees, and whether it's supported by my company’s corporate e-mail server. But all in all, it’s a nice wireless device.
