I get stutter but it's a niceness issue and mostly solved, for me only when opening pages in new window.

Names are not ideal, but there's a repositories with descriptions. Window shopping.

Besides, I like the N900 but it is not a girl phone, it's large. But it has keyboard for messages and games. Ask her if she would like stuttering music now and then or keyboard.

Also, music stutters when doing stuff at the same time. IPhne doesn't have that problem. How could it stutter if there is nothing else to drain resources?

As for online radio and stuff, you have an old firmware or a network latency issue. It flies here, even over 3g
