I have the mid 2012 model, it's okay. Definitely was never usable for me as a primary computer with 4GB of RAM. It was just something light that I can bring on the road. I find a Chromebook is better for this use case now. The keyboard is good, I will give the MBA that. But open Gmail in Chrome (with no other tabs or apps opened) and the MBA starts tapping out like that is some kind of big ask.
