The Blackberry World Edtion has some great features, but is missing some essentials.
Pros: The call quality and organization features are great. No restrictions on where you can travel. Good size. Reliable. None of the issues that Mobile Windows phones have.
Cons: There is no camera, which I use constantly The keyboard takes a little getting used to The track ball also takes some getting used to It is not as easy to sync to the office network as a Windows Mobile phone, especially if your company restricts the email server, as mine does
Overall, if you are a business professional and are using the phone strictly for business, this is a great phone. If you are planning on using it for both business and personal use, it may not be the best. I think I would have been happier with a different model of Blackberry and if my company would allow Blackberry use on our network.
