I was replying to a question on why one wouldn't "just get a MB Air/not use the screen"... not the article. How is this relevant? I don't say this to be rude, but this internet phenomenon of relentless pedantry is annoying. Things tend to make [some degree of] sense when your first reaction isn't to shoot from the hip. Mains batteries exist - most people should save the effort, get a UPS. Hackers on the other hand... it's kind of silly to ask why. The answer is 'because'.
