• You're right about hardware - sometimes it just is dodgy. But a tiling wm is a tiling wm.
• Developers looking after their laptops? That's asking for trouble. They know enough to be dangerous, but not enough to dig themselves out of the holes they're creating.
• I've never made linux as part of my personality - I've discovered it. We naturally lean towards things we're good at and get good at things we lean towards. I'll (hooefully) never initiate preaching of linux and its userspace, but if a conversation happens to go that way - I'll happily chime in.

Have a nice day!
