Funnily, my linux box with Steam is a better gaming platform than my last Mac was. I still apparently have to jump through hoops to play something like World of Warcraft or Skyrim, but there are an ever-increasing number of indy titles and a lot of those are quite good.
If I could get WoW or Skyrim running effortlessly on my Linux box, Apple and Microsoft could both fuck right off.
Doing a video upload to youtube and having the upload complete before I can finish typing the description in the video is also pretty nice.
I've also started shooting my skydiving videos with a 4K GoPro, and even when viewing the videos at 1080, the difference is pretty amazing. You can actually see air traffic (Canopies, wingsuit guys, nearby planes, etc) that would not have been visible with the old GoPro. There have been several cases in the past where I'd be flying my wingsuit and spotted planes or tracking groups below me that didn't show up on the video with the old GoPro, and you can actually see the things that I saw on the jump with the new one.
The trouble with money is it costs too much!
