Absolutely not is the answer to your question. Best Buy makes a lot of its money by selling these kinds of useless services to people who don't know any better.
I wouldn't pay the $150 to basically have them install an anti-virus program for you. As for whether or not you can make a DVD image of your own... I would shoot off an email to the manufacturer of the laptop you're looking to buy or bought, and see what they have to say. Also ask what they charge for restore media.
And while it's going to sound like I'm badmouthing Best Buy, and I suppose I am a bit... Just in general, those extended warranties and everything else they try and sell you along with something... Completely worthless. Maybe if you bought a big screen TV, and you don't want to have to make a claim on your home owners insurance if something happens to it... That's about the only real scenario in which it might be useful. Otherwise, complete waste of money.
I went to purchase a laptop computer at Best Buy. The guy was insisting that we buy this $150.00 package where they give us disks(it doesn't come with any) install anti-virus stuff that they spend 5 hrs. to install for us, and he says since it is vista you can just downlaod this for free anymore. He said for $60.00 I need to at least buy the disks to be able to install it.
Is all this really necessary? Should I be able to create a DVD of the hard disk image?
Anyone know what the "optimization" is that they perform?
