Definitely not worth it. Its price where I am (Asia) is about on the same level as 6300 and 7390, and significantly below N80. Just hold a while and its price will likely drop where you are.
I also think it's like a more refined version of N80. Much thinner, much better keypad. The screen's lower-res though a little bigger but frankly you can't complain about a QVGA screen.
