Has anyone received a replacement from MS in the mail - Does it come in original packaging (the customer service rep couldn't answer this ?). My Battery capacity dropped 25% in the past 2 months - ive only been getting like 5-6 hours vs. 8-10, and they agreed to replace the unit. That being said, I got used to the 5-6 hr battery life, and have been debating to bite the bullet and get Surface Pro - If im going to start new, may as well go pro. Either way, if it comes in original packaging, I can probably exchange at the MS store - does anyone know?
