In my mind the main thing that would deter you is the truly limited battery life. The N900 is so usable that all your expectations are immediately reset higher - I am personally caught with expecting my N900 to perform as well as this laptop I am using now running Ubuntu 9.10.

The N900 cannot do that and the main reason is that the battery dies very quickly (3-4 hours) when using it as a super portable laptop.

There are also quite a few bugs that make some basic things frustrating or crippled - two that annoy me the most right now are the bugged bluetooth file transfer, and limited sharing via Picasa.

Also keep in mind that Ovi suite does not support N900... version 2.2 of Ovi suite is in testing now and that will support the N900, when it is done.
