My daily driver is a 2014 Thinkpad. The only mod compared to stock is that I maxed out the ram. It's been an absolutely amazing machine, especially given that it cost all of $200 second hand (W540). I find it really hard justifying buying hardware that doesn't allow me to do anything that I couldn't do before. Up to 2003 or so I was always chasing the latest and the greatest but now I find that I can do everything I need on this old beast.
