Nokia N810 – Opinions please

Basically my laptop has just died on me and am looking for something to replace it.

I use my Mac most of the time and the laptop was only ever really used browsing the web while in bed or round a friends house etc.

Looking around at 2nd hand products etc (to keep costs down) I have seen the Nokia N810 and wondered whether this will be okay you just internet browsing, facebooking etc etc?

Does anyone have one and can maybe comment or is anyone on here selling one?

Thanks

James
