Buying a new motherboard to replace the Thinkpad is hardly a fix. Otherwise I could 'fix' my Thinkpad x200 by buying a x230. You could make a case for the ship of Theseus but it's more like you are taking off the captains wheel and replacing the whole thing and calling it the same ship.

I never got the appeal of those laptops either. It's not a Thinkpad, its an Chinese motherboard that is overpriced to get it working with a nice keyboard, and yet you'll still have to bend your neck to use it unless you're using the dock.
