I love my V7! I use it every day for programming, reading ebooks, checking mail, web surfing, and watching movies. I've had it for 6 months now and it's amazing!

I'd like to make sure I have the latest updates, but I don't want to lose any functionality. I actually use all three OSs on a daily basis. After reading through this board and a couple others I've become confused as to the latest available compatible OSs and which OSs break the others. Could somebody please answer these questions? Thanks in advance.

What are the latest OS versions that are compatible with each other?

What are the latest OS versions overall and what are their compatibility issues?

That's the V5.

I want to keep my V7 and just update the OS.

- What are the latest versions of each OS for the V7 that does not break other OS?

- What are the latest versions of each OS for the V7 (even if it's breaks other OS)?
