Should i trash my Nokia 1100

I want to get a brand new cell phone maybe a N91 of Nokia N-Series. But my uber strong Nokia 1100 don't want to give up yet, i've accidentally dropped it many many times, but still it keeps on working and never give up on me. It's really hard to let go of something valuable to you.

Here is the features of my 1100:

But take a look at the difference between this and the new N91. I've heard that Nokia will be launching the N93 next year.
