Small correction:

"Multi Generational Architecture - fast recover, no need for
transaction logs!"

It is not quite true - MGA has little to do with recover and
transaction logs. Netfrastructure is also MGA, but it has transaction
log and slow recovery. We have fast recovery because our versions are
on stored on disk and because of careful write technique that
guarantees that file is always consistent.

So, either "Multi Generational Architecture - you won't know what
locking is" or "Careful writes - fast recover, no need for transaction
logs!" or "Unique architecture - fast recover, no need for transaction
logs!"
