For those who like the idea of practically carrying a mini-notebook in their pocket, the E90 Communicator is one of the most comprehensive available. It won't appeal to everyone but despite the lack of TV-out and fax features, it is the best of business phones.

We like the idea of a large touchscreen but the Uniden GNS 8600 is a little too big to be practical, despite its excellent features. The lack of an internal battery, slow interface and high price tag all count against what could have been an excellent product.
