I work as a hardware tech for a fortune 500 company. We do support both types of laptops. All laptops have problems. I do agree that warranty is the most important thing in purchasing a laptop and IBM cannot be beat. Dell is just as good of a machine, but does not have the service that IBM does. I support over a 1000 think pads and about 400 dells. But again no laptop is perfect. There was a recall on several thousand IBM laptop drives and IBM made provisions to contact each individual and fix the problem. Also gave a free 10-20 gb hdd upgrade. The fix was transparent to the user, they reimaged and tranferred data. The bad thing about IBM (not sure on Dell) is that parts are so expensive once the machine is out of warranty. From a tech stand point i do prefer working on IBMs over Dell. The thinkpad seems to be more solid.
