Lenovo's service was great. They changed motherboard

Summary: I got the computer and during the first week it kept on crashing (blue screen). Although the computer is completely unreliable, Lenovo's service was great. They changed motherboard, but computer keeps crashing. Now I have to re-install windows, hoping it will solve the problem. I read the bad reviews, and still bought it - don't recommend others to do the same mistake.
Summary: After quite a bit of abuse my old X1 finally died. I live on the road and my machines generally take a fair amount of abuse. The constant banging around of being in a laptop bag, being taken out here and there, carried around by the keyboard and the non-stop banging around going through TSA checkpoints finally did the screen in. Until then, I thought it was the best laptop I've ever had.
Pros: Still runs like my old X1
Cons: Keyboard and track pad are pretty much unsuable
Everything went great until I hooked it up to a Dell U3014 ...

Summary: I have owned this laptop for about 9 months. In that time, the hard drive has failed twice and the wifi has been throwing a "limited connectivity" message for some time now. The most recent issue is the battery is now giving an error, will not charge, and the laptop will shutdown if the plug is pulled (goodbye to all the uncommitted data in my database project, and two large stored procedures I wish I'd saved).
Summary: JUNK. We bought 8 at work. 4 needed new motherboards within the first month. 2 of those that had the motherboard replaced had to have a 2nd motherboard replacement within another month. These "computers" have the motherboard of a tablet. You're essentially buying a tablet with a laptop sized keyboard and screen.
Worst design change ever. Lenovo took a great machine and made it useless.

Summary: The Gen1 X1 Carbon is a GREAT machine. Sadly, this turned out to be a Gen2 system where Lenovo, in what has to be one of the worst design changes I've ever seen, has replaced the traditional keyboard with one that is terrible for anyone that actually uses this machine to do something other than look at facebook. Worst keyboard layout ever! People use function keys! Didn't even power the thing on when it got here. Just sealed the box back up and returned it.
