Here is
another review, perhaps slightly less biased
The conclusion is so-so:
Chock full of promising concepts, the Nokia 9500 Communicator almost invariably fails in execution. A fantabulous display is hampered by poorly utilized screen estate; the first-class thumbboard by an ergonomic oversight; applications in general and the powerful browser in particular by sluggish performance; and PIM and e-mail synchronization by slow and poorly implemented local support as well as a complete lack of groupware support. Superb connectivity doesn't do much good when its full potential cannot be exploited, but for those whose needs fall within its stark boundaries, the 9500 will deliver the goods.
