It was a tough decision I'll admit.
Yesterday I paid a visit to my local AD and sure enough there was a Zero in the case. Hadn't seen one there before and it's been in my sights for some time now as my next pick up.
Alas I only had the funds for one big purchase. The Apple store was waiting so decided to make it this instead.
Apple Thunderbolt Display & 2012 13" MacBook Air, 512/8/2.0 i7.
The Zero will have to wait a little longer.
