Advice on my purchase

I have made the decision to buy a macbook but I'm a bit worried that I'm going to get it and by next week it is going to be old and defunct. Should I wait a little while for the release of Leopard (I hope it'll be a little while), or should I buy one now. I havent noticed any major differences between the two cats in reviews so far, apart from "spaces" and a new version of iChat. I would be grateful for any input, and should i bother, should i just stick with my old laptop?

Thanks,
Bard

You will most likely want to get 10.5 when it comes out. You'll know more about it after 1/9/07. If you don't mind shelling out another $129 when it ships then get the macbook now. I have the second gen macbook core duo and I'm confident it will last me a few years. Running 10.5 and most likely 10.6.

Thanks for the input, im in the UK so i think its about £90 (which doesnt sound that bad). I got the apple bug, only slightly worried that the key note is going to introduce something brand new but it'll prob just be showing off leopard (or the iPhone).
