7 Essential iPad Productivity Apps: "When I got my iPad, I gave myself a mandate: Don’t lug a 5-pound�MacBook around; instead, try to make do with the iPad.�For the most part, I’ve been successful. My MacBook hasn’t left the house since April 3, and for what I do (writing, reading, video watching), I don’t really need the horsepower all that much. I wouldn’t want to do a day’s work on it, but it’s great for getting work done on the train, on my lunch break, etc."
