This really is what I've been wanting for years.
The 2011 MBA was the best laptop I've ever owned. All the performance I needed (at the time), in a very lightweight package. Despite being so incredibly thin and light, it never felt like a compromise. All the necessary ports, a big enough display and a great keyboard.
Of course, I fell victim for the Retina-craze, so sold it for a 13" Retina MacBook Pro which never had the same charm. A great computer, but felt a step backwards in terms of design and portability.
Rumors of a "Retina MacBook Air" first started appearing in 2015, but when it materialized into the 12" MacBook, it was very much a compromise to me, unlike the MacBook Air. Needless to say, I didn't buy. While the 12" MacBook has become a much more viable option over the years, I still find the display to cramped and the 1 port too limiting.
Let's hope this new rumored 13" laptop with Retina Display will finally be the Retina MacBook Air I've been waiting for. Touch-ID would be icing on the cake.
