Summary: This laptop arrived yesterday, and the SSD was packaged separately - not installed. The installed hard drive runs Windows 8.1. The solid state drive has Windows 7 Pro, but does not boot when installed. Update (9/10/14): I contacted the seller, and he gave me instructions for changing settings in the bios to allow the laptop to boot from the SSD.
Summary: I like the computer. It is light weight. I can work on the computer unplugged for most of the day. I particularly like the digitizer that I can mark on my power point slide. I do have problems with the USB connections on this computer. They were from time to time disconnected for no apparent reason. I had to unplugged the USB drive then re-connected it.
Summary: Last minute purchase. I broke my X220, and needed a replacement fast. While the battery life dwindles next to my X220, the i7 and increased memory makes a world of a difference. The touch screen while nice, does require a high degree of precision. However, I have also noticed that several pieces of plastic are chipping off the computer; luckily the roll-cage helps keep the computer together!
Summary: We use these regularly for healthcare industry clientele. Quick, powerful, and no Windows 8. Sturdy and a very nice touchscreen. Unfortunately, Lenovo does NOT manufacture 9- or 12-cell batteries for these, so if you're unable to charge every 3-4 hours, you'll want to disable one core and hyper-thread in the system BIOS and use the ThinkVantage Power Manager to dim the display and operate in maximum battery mode.
Summary: This line of ThinkPad was required for my school this semester. When I turned it on, the first thing I do with my PCs is get the Windows Updates. Had a mess of trouble getting them installed. Moral of the story, do not connect the dock while updating. After factory restoring the computer 3 times, I managed to get them installed by booting to clean boot.
