My thinkpad's screen start flickering one month ago. It was just a column 1/4th of the width (maybe 1/6th, can't remember now).
I was horrified by the fact that I may have to buy another laptop, but fortunately, it was a matter of 100euros for the LCD.
Watch this for a nice guide on how to change the LCD without messing with unnecessary parts. And enjoy a really nice soundtrack https://www.youtube.com/watch?v=7RwO6ZlyzGA .
So, and today I read in /r/emacs that the CTO of Opera software is a heavy user of emacs, and owns an X220. That's what he says about X220.
