Sure, I understand TechRestore's message that your Mac can be restored to its former working condition just as if you'd gone back in time. But let's think of what other Mac-related pursuits we could use it for: for example, one could head back in time, buy up G4 Cubes, and resell them at a later point in time when people thought they were worth slightly more than they originally sold for. Exploit the irony.
TechRestore is also demoing their . For $199, they'll take high-quality sandpaper and rub down your screen for hours. After they vacuum out all the shiny dust, you're left with the highly-desired matte finish. While I like envisioning that, the truth is they replace the screen, remove the glass covering, and even replace the bezel for a brand new display. It's a good option for those that can't stand looking at themselves.
