A pretty detailed explanation of the current situation and what will happen if the judge does find (and will) Google guilty is already given by Engadget’s Nilay Patel, who happens to be a copyrights lawyer previously;
Link: Android source code, Java, and copyright infringement: what’s going on?
His view: Google is in trouble.
Oracle will charge Google and probably all the handset manufacturers a licensing fee for every Android handset shipped.
Which I will argue, will be actually a good thing for Android lovers.
Making Android into a product that actually costs money will probably result in the following situations;
a. Android will probably become as expensive an mobile OS as Windows 7 is, and manufacturers will no longer stuff Android onto handsets with shitty hardware that are not capable enough to support the OS anymore, simply because they will have to pay for it. Android will only be reserved for higher end handsets that can support it, and justify paying the licensing fees for that particular handset by the manufacturer. Better hardware on Android means a much better Android experience for all Android lovers.
b. It will paint a much clearer picture of how influential Android support by consumers are. Right now the majority of Android market share is probably made up by the millions of cheap arse 0-dollar handsets whose owners know nothing about the OS that runs inside of these devices. If Android is strictly a smartphone OS, that ensures only people who understand what Android is will be buying Android devices for use.
