Will Mountain Lion run on my MacBook? (And do I want it?)

Hey,

So I have two questions. Firstly, is my MacBook too old for Mountain Lion? I think it's a January 2009 model. Lion runs ok on it but it crashes occasionally. On the other hand I've heard Snow Leopard runs really well?

So that's my second question. If it does run on my MacBook, would I want it anyway? Considering that Lion crashes sometimes and doesn't seem that amazing, maybe Mountain Lion would crash even more? Plus the only features seems to be things like iMessage, but I don't have an iPhone. I'm not sure the upgrade is worth it for me..

Any thoughts?
