Overall, I love my X1, but I have had so many problems that they finally replaced it with a brand new machine. Premier support is mandatory for Lenovo IMO, in spite of the problems, I never once had an issue getting someone onsite to repair it and they assigned a local case manager to sort out the replacement. On the Lenovo forum I read a lot of stories from people with similar problems, but with basic warranty they reported getting a run around, being without a machine for weeks at a time with it went back and forth to the depot. A YMMV..
