I had a Thinkpad that was rock solid for years. IBM/Lenovo/whatever even replaced the motherboard for me for free, out of warranty. I put the service request in Monday night, got the return shipping box Tuesday morning, and got the repaired computer back Thursday evening. Unbelievable customer service. I don't use it much anymore, but it still runs fine. I think it's a 2006 model, IIRC.
