By now, most tech sites have talked about Boot to Gecko, following MWC announcement and demos, and how it’s based on standards from the open web to build the entire user interface.
One thing I would like to stress is that more than being tied to the open web, Boot to Gecko is also open source at its core. If you want to build Boot to Gecko today and use it on your phone, you can. Sure, you may have some difficulties if your phone is not a Galaxy S2, but I’m pretty sure the community at large (XDA and others) will soon have a solution for a lot of other phones or if you are skilled enough, you can do it yourself. And that is the great strength of Boot to Gecko’s open source nature.
And that strength is also a major difference with Android. Android is open source, but it also is developed behind closed doors. Boot to Gecko code has been available on github for months. Android 5.0 Jelly Bean, which is expected for the end of the year, has been in development at Google for months too. Want to test it? Want to see the source code? Want to participate? Well, you’ll have to wait for it to be shipped on an actual phone, since Google doesn’t release the source code until then.
