Google announced they’re only going to release the Android source code twice a year from now on. It’s barely open source. And completely controlled by Google, unlike desktop Linux. I only really see this as a negative, because the last thing we need is for more software developer energy being dedicated towards proprietary platforms. And Android devices have horrible custom firmware support. If anything, Android desktops would be more proprietary than existing ones which are the easiest computers to customize currently. But these Android computers will probably by ARM devices that have a similar story in terms of it being hard to run a different OS. I think ChromeOS is already sorta this way.
