I have the Pearl 8100 and LOVE IT! It was my first BB and it's taken me a year and a half to figure somethings out. I am happy with it. That being said I am ready for an upgrade and love the look of the curve. I convinced my buddy to get the curve and it has more features I may not use but the full keypad is nice and it's slim!
Forget the features it looks nice!
It's all about the accessories!
Seriously, you'll find alot on this forum with comparisons since most models have been discussed as to which is better.
Good luck and may the force be with you,
