Computing outside can be a real pain in the thumb drive. The ambient light blaring up against that LCD screen can make it darn hard to see. Sure, you can try using a bellows, or even some sort of screen shade, but as the light shifts throughout the day, sooner or later you’re going to find yourself playing cat and mouse trying to see, unless you bury your head inside the bellows and then it’s darn near impossible to read, much less type like that.
