They're rubbish laptops at rubbish prices from rubbish companies.
The thing they wont mention is the bus speed of the processor and memory on the motherboard.
My first question would be why you're looking at getting a laptop - do you use it out the house? Laptops are generally more expensive, and are much slower than the same-priced desktop alternative.
These laptops Curry's give away are probably less than £300... you'll end up paying double that over the year for it.
