For the last few years Ive used new 15'' Macbook pros. I switched to a 2012 macbook air a few months ago.

Its been so good in comparison, despite the smaller screen, that Im now thinking of buying another and saving it for later use after this one dies.

I was lucky enough to have a stash of Nokia E71s that lasted years. These earlier model airs remind me of them. They simply work, and do the job without fuss. Battery is still fine too.
