When I get a chance, I enjoy watching how someone else works on their computer. It’s great to pick up tips and tricks that the user in question might not even consciously recognize they’re using because they are so ingrained in their muscle memory. I also really enjoy finding out what software they use (particularly for Mac OS X or, to a much lesser extent, iPhone) because I always like to try new tools and hopefully find something that works better for me. Oh, and gadgets. Mmm, I love gadgets.
The Setup is a site dedicated to asking people about their setups: hardware, software, gadgets they carry, etc. I thought it was a fun “bunch of nerdy interviews” (as they call them). Recommended.
