DELL customer service bad product Internet, Nationwide

I have had an Inspiron 1721 for 2 and a half years. I have the best warranty that Dell offer, so I guess that was the only good decision made buying this computer. The warranty is up 12-16-10. Since I've had the computer I've had to replace numerous parts, some repeatedly. I have a lemon if there ever was one. Dell won't even consider replacing the computer. I think it is because they are trying to run my warranty out. I will never buy another item from Dell. I use my computer for work and have been without it for more than 30 days since I've had it, due to repairs. Everyone I know that needs a computer, I will do whatever I can to push them to something else. I'm sure there may be good Dell stories, but I don't have one and they have done nothing to show there dedication to their product. Buyer Beware!!! here is a list of replaced items
