After Lenovo's much botched intro of the X1C people are finally starting to receive their notebooks ordered in mid-August.
If you search and read end user reviews and comments it confirms the X1c display is poor with their famous dull 'screen door effect' low quality panels, heat is fair, fan noise loud, even at idle.
Numerous owners have returned their X1's, some mention considering the Air, many others have sent their brand new notebooks in for repair due to QC issues.
For a touted 20th anniversary notebook there's a lot of unhappy people.
