Re: It's good to have choice
If all mobiles and tablets ran Android, that would be fantastic news for consumers.
You buy an app and it continues to work on all your devices. There is nothing to tie you to inferior hardware like Lumia or iPhones anymore, you can just jump ship to whatever is better.
Android is also opensource, Google are the maintainers, but anyone can (and does) contribute.
I trust Android and Google to do he right things way above Apple, Microsoft, Amazon and others, and their closedsource, lock-in tactics.
