The good: The Nokia N900 offers a powerful mobile Web browser, plenty of storage, a 5-megapixel camera, and an ultrasharp display. It's also fast, multitasks well, and has excellent call quality. Wi-Fi, 3G, Bluetooth, and GPS are all onboard.
The bad: The user interface isn't very intuitive. Ovi Store for the N900 isn't live yet, limiting the number of available apps, and it doesn't sync with Exchanger Server 2003. The phone is a bit bulky and not all apps work in portrait mode.
The bottom line: While it has yet to reach its full potential, the Nokia N900 is a powerful mobile device with excellent browsing capabilities and vast customization options. However, its unintuitive interface and other limitations make this a smartphone for tech enthusiasts and early adopters only.
