... A lot of research... on the MacBook Air 11"? I find it quite difficult to do that when I'm writing. With my old MacBook Pro 15", I could have two pages side-by-side and still be able to write, but this is definitely impossible with the MacBook Air 11" (Even a single page is straining it).
I travel a lot, so portability is a key issue for me. When I first switched to Mac, in 2008, I bought a MBP, but, while it was a great computer, it wasn't really comfortable to travel with as I found it on the heavy side.
In September 2010, I bought a MBA (13", the 11" wasn't introduced until later that year) and loved it; a terrific computer, it was easily the best computer I ever owned. Earlier this summer, I decided to get a new MBA - the old one still works perfectly well, my brother is set to inherit it, but three years is my cycle as Applecare is close to expiring, so I ordered a new 13" MBA CTO.
Unfortunately, it wasn't ready by the time I had to return abroad to work, (I work abroad), and so, as an emergency stop gap measure, I bought an 11" MBA refurb. Initially, it was more as a sort of try out, as I wished to see what the 11" was like.
As it happens, my eyesight is quite poor, and I wear glasses, and - while I loved the form factor of the 11", and the utter portability of the device, I must admit I feared that the screen would be too small for my purposes, as I write and research quite a lot. Much to my surprise, I have to say that it is a superlative little computer; blazing fast, the screen is surprisingly good, and the memory (I got a version with 8GB RAM and 256 SSD) delightfully capacious. Actually, you can call me impressed.....
