I like the list and it seems appropriate. When I got the camera I had one of the slowest SD cards possible (Class 4), since then I've gotten a UHS-I card and what a difference. Since I received the UHS-I card, the camera doesn't lockup, time to shoot is much, much better and the battery is lasting longer.
For example, last night I went out to watch some bands for a few hours and I took over 300 images and the battery didn't run out (the battery wasn't even full when I started). I'm shooting with all of the fast startup stuff turned off, which with the UHS-I card I found I just didn't need and I have auto shutoff set to 5 minutes.
I think the lockups I experienced before the new card might have been:
1. trying to start the camera by a quick press on the shutter (now I hold it down slightly for a sec)
2. because the sd card was so slow, startup was slower and I'd give up before waiting long enough. Not sure but works great now...
