Somethings I've noticed and read about this whole deal. First Apple sued Samsung, specifically Samsung's industrial design as it pertains to some specific older devices as well as the TouchWiz UI elements that Apple feels that Samsung copied from Apple.
First the GS3 as well as the Note 10.1 were specifically excluded from the law suit -- this is important.
Second, the jury found that the GS2 amongst other phones violated trademarks so this is more about old phones that really don't concern us anymore.
Third, the infringing parts of the TouchWiz UI that apple doesn't like just means that at the worst Samsung will have to migrate to more of a vanilla Android experience -- isn't that what many people want anyway? I see this as a move to have more 'Nexus' like devices than anything.
Fourth, the judge specifically instructed the jury that damages could only compensate the parties to the effect of lost revenue due to infringement and specifically could not be punitive in nature. This is an issue as at least one juror has gone on the record as saying that the jury awarded as much as it did to "send a message" to Samsung that copying is bad, they can't do that. Also in the 700 some points that the jury managed to deliberate in record time they handed back damages with regards to the Note 10.1 having infringed, the Note 10.1 was specifically excluded from the lawsuit as having not infringed.
This case is going to go on a very long time, don't worry now, or realistically for years, about Android or Samsung having to make any changes. Until the case is settled the likelihood of anything substantial happening is slim. Get your SGS3 and enjoy it, I made the switch 3 weeks ago and wouldn't go back.
Look at the worst you'll have to room/ROM and go with CM10 or some other JB ROM because Samsung may have to pull something from TW but is that the end of the world?
Personally I hope this makes it all the way to the Supreme Court and that it manages to rip apart patent law as it exists today. The fact that you can be granted patents on such broadly defined ideas as 'rounded rectangles' is nuts!
