I need to upgrade my 2011 MBA and had my sights set on a Surface Pro 3. Mainly because I like the fact it can double as a second tablet (I have an iPad Ai r2), my wife owns an iMac, and it would be nice for us to have Windows 10. Anyone else in my position? This is a tough one because for relatively the same price, both units have similar specs right down to the 12" 1440p display. The SP3 costs a little more when you buy the cover, but with the various sales on Microsoft products (and the lack of sales on Apple products), it is a wash.
