My 6 year old laptop has died (most likely hard drive) and whilst this may be repairable there are so many other 'quirks' with it it's probably not worth the bother.
Don't need huge amounts of processing power, prefer something that's going to have decent battery life (>3 hours) and not be kicking out huge amounts of heat (the fan hardly ever runs on my current laptop). 14" widescreen would be my preference, needs to be fairly portable but it's my only computer so don't really want anything smaller than this. Don't really have any further requirements, in an ideal world I'd get something identical to what I have now with a slightly faster processor and a bit more ram but it doesn't seem to exist from the quick look I've had.
Any recommendations? (I've not decided on budget yet)
