Welcome to Engadget's back to school guide! The end of summer vacation isn't nearly as much fun as the weeks that come before, but a chance to update your tech tools likely helps to ease the pain. Today we're getting down to the very important business of helping you sift through laptops, and you can always head to the back to school hub to see the rest of the product guides as they're added throughout the month. Be sure to keep checking back -- at the end of the month we'll be giving away a ton of the gear featured in our guides -- and hit up the hub page right here!
