@Anonymous coward re warranties
The UK legal situation is that warranties are IN ADDITION to your statutory rights which are laid out in the invaluable Sale of Goods Act 1979 (mainly Sections 13 and 14). Warranties exist between the manufacturer and the customer, but the contract (enforced by SoGA) is between the retailer and the customer. Your first resort should always to be to deal with the retailer under contract law - NOT the manufacturer with whom your relationship is much less strong.*
Goods out of warranty may still be found wanting under SoGA in that they may be defective or simply not fit for the advertised purpose.
SoGA does not lay down a maximum term for when it can be applied, but IIRC from my law lectures it is something like six years - but on a diminishing scale. Naturally wear and tear and reasonable lifetimes have to be taken into account before any compensation can be awarded. Interestingly, any goods that fail within six months of purchase are considered to have been defective when purchased (this applies from March 2003).
If goods fail after working for a while you are *not* entitled to reject the goods and obtain a refund; but you are entitled to a repair at the retailer's expense or a replacement item (unless the cost of the repair would be disproportionate or a replacement item cannot be obtained in which case you are entitled to a refund).
If goods fail immediately, do not work as advertised, or a reasonable amount of work cannot get them to work, then you are entitled to reject the goods as 'not fit for purpose' and either obtain a replacement or a full refund from the retailer. The retailer may not charge for this.
* Although EC law is strengthening the legal obligations of warranties and this situation may change in the future. Certainly 2 year warranties are becoming much more common as companies harmonise their conditions throughout the EU.
