I'm guessing there's a few of you out there with children heading to Uni this year. No doubt they'll probably be wanting a MacBook Air or Pro. Personally, I'd sell the Beats to get a nice discount on the Mac.
Here's an example. MacBook Air 13" is $1569 with the $80 education discount. Solo3 RRP is $460, but $330 is the cheapest available. You can probably get $250 if you sell them. Making the MacBook Air $1319.
You can also get an iPad Pro for $1069, but you only get BeatsX (worth $187) free.
I've posted this as a deal on Choice Cheapies, there's more info over there.
