Acquired a Thinkpad X230 over the weekend and have been hacking on it. I like the size and light weight (lightest Thinkpad in my collection.) Maxed out the RAM and put a decent SSD in it. Also replaced the slow old wifi card with a spare Intel AC card I had lying around, which makes a big difference. Installed Qubes and Heads; cool approach and very secure-feeling, but may be overkill for me. The adventure continues!
