With all due respect to Steve Jobs, I’ve never been convinced by his stance that 7″ tablets are a bad idea. But I haven’t been able to mount a convincing case that he’s wrong, either. The original 7″ Samsung Galaxy Tab suffered from using a version of Android meant for phones. RIM’s BlackBerry PlayBook had even bigger problems. Neither one was a 7-incher you could use to refute Jobs’ argument. On the other hand, though, it was factors other than their screen size that hurt them–so I continue to hold out hope that someone will make a 7″ tablet that’s just plain nice.
