Umm, yes, they do have real competition, just none of them have gained any traction yet. Maybe they could try holding back all of their stock to create lineups. If it works for Apple, it can work for them too!Right. Because the iPad has real competition? No. If someone wants an iPad - they aren't going to buy something else.
And again, that is faulty logic. If you use that logic, then you would expect no lineups for iPhones, as Apple certainly has major competitors in that space. Yet the same line ups are there for iPhones. Sorry, your logic just doesn't work.
