Just purchased myself a pair of Nike Free 7.0's and all I can say is: WOW. These shoes are so comfortable -- I felt like I was not wearing any shoes at all! These shoes are very lightweight (10 oz!) and feel incredible. I think I made a good choice even though I would never pay $85 for a pair of sneakers, but it was definitely worth it. I think these will last awhile and will also help my running performance.
