I don't like Lenovo. Their laptops have steadily declined by every metric I care about since the X220. But Thinkpads are still better (by those same metrics) than anything else I've come across.
Would be willing to buy something else. Anything else. But most other laptops out there have even worse keyboards (which I deeply care about), terrible form factors, specs that are stuck in 2010, awful support/warranty, no Linux support, or all of the above!
If someone builds something I'm happy with, I'll buy it. Price is not an issue. My laptop is my toolbox. I want it to work the way I like it. If it breaks, I need to have fixed preferably today, but tomorrow or the day after can be acceptable as well. That basically leaves Lenovo & Dell.
