Although I have heard some good reports about Dell, my laptop, bought from them a year and two weeks ago, has just conked out. It's not been heavily used, but the hard drive has gone kaput.
I've looked on the Internet to see what can be done and have found several reports of similar problems with Dell computers. It may be that I've been unlucky - one generally hears more from those who have problems than from those who have none - but I'd check out what other people say before spending your hard-earned cash on one of their products.
