Claudiu, Version2 is the updated version with major improvements..
From the factory it will have an orange emblem[sticker] on the left side of the keyboard..

There is an update available , but I have been unable to locate it..

I want to save the Version2 update for future use[I know I will get another VA, but I want a Version2]..

If you don't have Version 2, don't worry about it..If I don't tell you the differences...you won't miss them..

How is your manual reading going?
