Re: Apple's design is slipping

It's not that the design is "unreasonable" or "out of spec", it's the use case of that design that's causing the concern.

The backlight voltage line being directly next to a signal line doesn't melt traces or cause any sort of problems... until you let a user get near it and (inevitably) spill liquid onto the device. At that point the liquid is allowed by the case layout to reach the connector where it either directly shorts the backlight voltage to the signal line, or corrodes the connector leading to the same result.

So what? Well the signal lines don't have any protection built into them, and as they lead straight back to the GPU in the CPU on the newer models - your entire laptop is immediately dead.

Which would be easily avoided by, say, not putting the backlight voltage next to the signal lines?
