I love my Lenovo ThinkPad. For a laptop, the keyboard is amazing and I have been using it for 4 years now without any major issue. I did have the CPU fan die on me, but with Lenovo's practically 10/10 repairability score for 40 bucks I overnighted another CPU fan, just unscrewed the back and replaced it myself.
I think the X1 is a bit overrated - I prefer their T-series laptops for repairability and durability. You can generally pick some coming off of a corporate lease for a screaming deal.
