Why PM? It's better if everyone sees.
Are you suggesting that we make a new competitor for Android, or for Android phones?
While, in principle that would work, there are several concerns with each one that include, but are not limited to, resources.
There's also the issue of, android is great because it hooks up to your gmail, which is almost ubiquitous now. If we made a new OS, it would not be able to compete with that. Apple and MS also have that for live and for apple-cloud-stuffs.
FIRST they got a userbase, then they provided hardware to integrate with it.
If you're saying we make handsets, then the issue is startup capital. It would be expensive as hell to get around all the patents, not to mention actually getting the machinery to manufacture phones. It's CHEAP for them to make the phones, but it would be expensive as HELL for us. They've got wholesale deals, and in some cases OWN the companies that they get parts from.
Essentially, making handsets would make them have to be priced well over a thousand dollars.
