I have about 5 back in my office- One from 2005 that has AutoCAD on it I still use once in a while when I need to draw a plan for something. The other 4 just died a slow death with one going more than 12 years before I gave up on it- The @ key would not work unless you hit it about 20 times. I was just using as a screen to look at data for appraisal work. I've tried Sony- Dell and Acer. Acer has been the best of any- many years of service for 2 earlier units 09 - 2000- to currently using 2 from 2019 and 2021 that still work great.
