The above mentioned "premium fatal flaw" in this case is the terrible internal wifi, but a micro-usb wifi has corrected that. I also fixed IMO the glossy display with a screen protector. Other than those two issues, I really like it.
When it's finally time to replace it I'll be looking at Microsoft or Dell. Maybe even Apple or ASUS. Probably not Lenovo, because they seem to be trying to destroy the Thinkpad brand. If I had to buy a computer right now without further research it would be the Dell XPS 13.
