I would reccommend the warrenties. It is worth is, as an example, one of my clients has a Dell latitude and the motherboard went out on it 1 day after their 3 year warrenty. It is like it was waiting for it, but luckly they had purchased 3 more years 2 days prior. so they got a free MOBO which would have cost them a couple hundred dollars (esitmated 400 after installation and configuration).
