Marco Arment:

“What I hadn’t considered was that even though I had common tasks that could fit within the MacBook’s limited specs — email, writing, chat — all of them required a lot of typing. Oops.”

That’s one of the reasons why I decided to go for a Macbook Pro 13" as replacement of my old MacBook Air 11", despite of the weight. All my work has to do with typing, be it in a browser, a terminal or even in Word.
