Out with the old, in with the new. Course, if you're okay with the old, you can usually pick it up for cast-off prices. Like the previous-gen MacBook Air, which MacMall is dumping for $1150 after a $100 mail-in rebate with free shipping. To sweeten the deal, you also get Parallels for free after rebate. Not too shabby, especially considering that these are brand new, not refurbs. (Not that there's anything wrong with that.) [MacMall via Tech Deal Digger]
