I'm actually wondering what would be more reliable: a physical button or a digital one. I would like to see a comparison.

Of course, one could argue that in both cases it depends on the implementation. Nonetheless, I think it's fun to think about what kind of buttons would the average person prefer, when their life is on the line.

I was thinking the same thing - sure, it's cool to have a glossy touch screen and futuristic touch panels, but I can't count the number of times touch screens / buttons have gone wonky on me with everything from my cell phone, to my tablet, to my microwave, to my fridge, whereas the light switches in my house are about 50 years old and have yet to let me down...

I'd find it really surprising if touch screen buttons are more reliable and/or more preferable to astronauts in a space suit.
