@apt-get_update oh... you are a smart man!
Me myself i own several Lenovo products. Thinkpads and a smartphone. And also i HAD (they died) several apple products ...
Guess what still is working an usable!
One thinkpad is my dedicated mobile server. It spurs like a little kitty and never stops. Currently i walk around with a Lenovo VIBE smartphone and i do things with it that iphone users can only dream about (if they have the creativity at ALL to realize the possibilities).
I had the Carbon in my hands a few weeks ago. I like it.. it is not top of the line like my laptop HP elitebook made from magnesium (aluminium is for kids and airplanes) and only costed me 4000dollar... but that lenovo X1 is very VERY decent.
Good luck man.. .and Louis Ross can fix it... 100% sure
