I bought another battery... I change it if I use the N900 for 5-7 hours, and will use the other one. That's not much of an issue. However, you can do some things to improve battery life.

It does have MMS... I really hate it when stupid people talk about N900... It really pisses me off! N900 is not a phone, which comes with everything installed by default, and you can use. That's what makes it different. That's what makes it a computer.

Now, say the next thing... Processor speed is 600 MHz in your opinion, perhaps.
