This old dog is regularly learning new tricks, even though I find change as difficult as just anyone, I bet.
Part of it is the job: I feel like I can't legitimately claim that "x is better than y" if I don't keep checking in on "y" to make sure things haven't changed. So one of the thing I do regularly is to continually reevaluate, well, just about everything. The hardware platforms I use. The apps. The services. My work flow and daily work habits. Whatever. I've literally been doing this for over 20 years.
