Spuds: IIRC, the consensus on the forum has historically been "If it ain't broke, don't fix it". Unless there are good reasons for updating a driver, it's generally best to leave well alone. Don't do it just to keep things all nice and up to date. Personally, I stay well clear of these programs that claim to be able to find the latest drivers for your system.
In summary: you say you're "lazy" - I'd say you were (if inadvertently...) "sensible". :-)
