Lots of good apps here, but it depends what you want.. have a look in app manager under settings, if you haven't got many options you may need to add more repositories, search the forum for a post on how to do this, but beware of testing and dev repositories as the software there can seriously screw up your phone if you're unlucky.. The n900 is a great device but you have to put some work into finding stuff and getting it customized to your liking.. sorry i jumped on you earlier but your approach was not good..

Hope you find what you are looking for

edit: given tone of your last post maybe i'll reconsider my apology..
