Gawd 'elp us!!! I just updated a new (used - ain't eBay marvellous?) 
laptop to OS X.6.3 with the auto software update download this very 
day. Nearly 800+ MB.

Oh well, the same again but this time I'm downloading the combo 
package to apply to all three machines (we have one more to update 
from X.6.2). Just under 900 MB.

When will it end? Remember OS 7.5? ;-)

Cheers, Geoff
