All throughout August, we brought you our top picks for smartphones, tablets, ultraportables and more. We end on a sweet note with our final back to school guide today, but our giveaway is still running strong. If you haven't done so already, now's the time to leave a comment on each of our 14 gadget guides -- as well as our sweepstakes homepage -- for a chance to win one of of 15 tech-filled goodie bags. The contest runs through noon (ET) on Thursday, September 12th, so get your name in before the new semester gets too crazy. Good luck!
