That's a real shame, because ThinkPads used to be excellent laptops. My last Windows laptop was a ThinkPad T42 (last one made by IBM before Lenovo took over) and it was rock solid, the best Windows laptop I had ever owned. I had always assumed that if for any reason I needed to leave Apple products behind, I would get a Thinkpad again and maybe install linux on it.
I wonder fi the problem is the hard are, or Windows? Maybe the Yoga would run better under Linux?
When keyboards go from the best you have ever used to crap, it is hardware. Lenovo has lost their way!
