I used the thinklight a lot in college when I'd want to do homework in bed with the lights down low. You could both read papers and see your keyboard easily. The backlit keyboard really killed off the thinklight as I'm sure that was the primary purpose of it. I had an X61 tablet, X200 tablet, and a beefy T420 I used in college. They all got beat up in my backpack, anything plastic around the edges was cracked but they all performed dutifully. I only replaced my X61 because I finally had to use 64bit software for school. The T420 was too heavy to carry around all day and I wanted the tablet feature for homework so I bought the used X61. I still use my decade old T420 but I really wish I had sprung for the high density display as websites think I'm using a mobile device at 1366x768. There are ways to upgrade but I don't think I love my old Thinkpad that much to put in the effort.
