I agree that Lenovo needs some work in their support department. However, I've owned a T61, and just bought a T400, which is, without a doubt, the finest laptop I've used (and I've used quite a few). Great features, built solid, and the best keyboard I could ask for on a laptop. Plus, Lenovo has tons of discount programs that brought my laptop several hundred dollars below what HP or Dell could offer.
I'll give Dell credit for having the best business support compared to Lenovo, and they make good laptops as well. And, I'd encourage you to call Lenovo customer service on the extended warranty thing. However, the product itself is pretty darned good, especially considering they cost half of what ThinkPads originally did under the IBM brand name.
