An anonymous reader writes: One of the biggest interesting notes from Apple's recent quarterly report was that iPad sales are down. Pundits were quick to jump on that as evidence that the iPad was just a fad, but there were still more than 16 million units sold. iPads, and the tablet market as a whole, clearly aren't a fad, but it's also unclear where they're going. They're not convincingly replacing PCs on one end or phones on the other. Meanwhile, PCs and phones are both morphing into things that are more like tablets. New form factors are often successful or not based on what they can do, and the iPad hasn't done enough to make itself distinct, yet. Ben Thompson had an insightful take on it: 'This sounds suspiciously like the recommendation that the only thing holding the Macintosh back was its inability to run Apple II programs. It’s also of a piece with the vast majority of geek commentary on the iPad: multiple windows, access to the file system, so on and so forth. I also think it’s misplaced. The future of the iPad is not to be a better Mac. That may happen by accident, just as the Mac eventually superseded the Apple II, but to pursue that explicitly would be to sacrifice what the iPad might become, and, more importantly, what it already is.'
