|Take a look at the Acer 7551G (not the 7551)|
Would think for a 5 year warranty, you would have to pay an extension fee.
Often this must be opted for, fairly quickly after purchase. However, this should be investigated, as here in the UK, the retailer will try to sell you this at the time of purchase and it may not be as good a price as that of the manufacturer.
Again with Laptops, the better repairer is most likely the manufacturer.
On ease of use, it is rather down to the operating system, which presumably will be Windows 7.
Please advise back what you find/think.
Good Luck - Keep us posted.
