1366x768 TN display low resolution and very poor quality. Poor contrast and viewing angles, and won’t let you fit much onscreen.
Disappointed to see this in a $779 laptop, either new or refurb.
IMO the T560 should be bought configured, with the highest priority put towards upgrading to the 1920x1080 IPS panel. Choose that before the i3 -> i5 CPU upgrade because it will be more noticeable, and do memory/SSD upgrades yourself because it’s cheaper. Avoid pre-configs with 1366x768 unless you are specifically planning to replace the LCD yourself.
See http://reddit.com/r/SuggestALaptop/ and http://reddit.com/r/thinkpad/ . Can be a great laptop, but they’ll all recommend only buying this laptop with the 1920x1080 IPS display.
