Tick-tock like model for Google?
Sometimes Google releases a new Android version in a few months and sometimes it takes a year to release a new version.
Intel releases a new processor model (nearly) every year. First they release a tick: a shrinking of process technology of the previous microarchitecture, and the next they release a tock: a new microarchitecture.
What if Google used somethink like this for their stuff?
Lets take a look at Android
Android 1.0: 2008 (September)
Android 2.0: 2009 (October)
Android 3.0: 2011 (Februari)
Android 4.0 2012 (October)
What if they released a major version every year with new stuff and a little improvement inbetween?
Every major version would be a Nexus release, and every version should be shared with the manufacturers 3 tot 1 month before release.
I use juli as starting point because the I/O stuff is released then
Say they used this from the start (With A and B for the first 2 versions)
