You don't have to wait long if someone wants to invest the capital to do it. It won't take nearly as much as it cost Apple or Google to get to where they are today because the technology can be bought off the shelf now, with much of the software in open source.An how many decades do we have to wait for that? Should we in the meantime let Apple and Google rent seek without competition? You can do that in the US if you want. Your government, your rules.
The fact that no one wants to invest the capital should tell you something. Smart capital is being deployed in areas where the payoff is potentially greater. Those are areas unknown to people who lack the ability to innovate and believe their government should slice off pieces of Apple's pie and feed it to them like they are helpless children.
So, if you wish to see Apple have more competition, maybe you should innovate and provide some competition. It does no one any good for you to whine about competition when you can't compete.
By the way, understand that behavioral marketing studies have shown that people only want two or three choices in any given category. They don't want 25 different brands offering relative undifferentiated substitutes for the same product. So, don't be surprised when there are only 2 or 3 me-too competitors to Apple's App Store that rise to any prominence in any given protectionist political region. I wish it were different, but I try not to let my wishes cloud scientifically verified facts.
