Re-setting MacBook Air mid 2011 model with Mountain Lion installed - what will happen

[machappymeal]

I have aMacBook Air mid 2011 model with Mountain Lion installed.

If I was to sell the Air and reset it (or wipe the drive) what will it revert to for the new owner?

Just curious

It depends on what OS you (or the new owner) re-install(s) on it.
