Is Mountain Lion available in disk form?
No, only by download. Apple has not announced a flash drive form as of yet as they eventually did with Lion.
Apple stated a while back that they would not be offering Mountain Lion on a USB flash drive. Of course they could always change their minds, but at this time it appears that downloading will be the only source for Mountain Lion.
I know, and seem to remember Lion started life as download then flash drive was added...unless memory is failing me, which does happen, can barely remember breakfast
Who knows, all we can do is react to what the powers that be decide to offer up to the masses.
