New Laptop

I badly need to get a new laptop for work. Every time I fire up my current laptop, it makes a noise like a tumble-drier (and actually gets about as hot as a tumble-drier). It is about two years since I had this laptop, and that seems to be about the lifetime of a laptop (I still have a desktop that is 10 years old). Laptops naturally do not last as long as desktops and besides, there is so much technological advance in two years that it is almost a necessity to get a new one.
