I haven't seen a BSOD on Windows in years and OS X certainly hasn't crashed on me. iOS? No crashes on any iPhone I've used or my first-gen iPad. Now, granted I'm not the strongest fan in the world of Windows, but it's a heck of a lot better than it used to be.

The point is, most aircraft have redundant systems--like three hydraulic systems, two to three electrical systems, multiple computer systems designed to work in parallel with each other using multiple sensors simultaneously. I can promise you the display has a minimum of two drivers and two complete sets of screens behind that glass. Even if one side went dead, the other side should still work. As I said once before, if everything goes, the plane's done for anyway.
