This device is...

great for those that are already familiar with *nix environment and frequently use it for their work or home environment. It'll fit very well and pretty much no other mobile device can offer the same level of functionerformance:size as the N900 in this regard, at this point in time.

good for those who like to tinker. for those who really value opensource, open standards and their digital freedom above other things.

below average for those who are looking for smartphones in the popular/conventional sense. for those people who would like to get functions out of their devices with minimal fuss.
