Fair enough, but isn't the point that some applications (ones central to the device like the browser, email, maybe calendar now?, book app?) can't be duplicated? You can't write Firefox for the iPad or submit Opera mobile. Or, I suppose you can, but Apple won't accept such items, will they?
So in that sense, the mere number of apps is irrelevant. My point was that the experience is very, very heavily controlled and that many people turn out not to mind that when it comes to such devices.
