OK, for all you longtime apple veterans, I would like a historical analysis of how much apple has "sneak-peaked" in the past. From my recollection, the preview of Leopard actually was pretty complete with them even having to take away major components on initial release (time machine over external hdd linked to airport extreme, and ZFS support which was ultimately canned). Everyone is saying that we haven't seen 1/10 or ____ (insert fraction of your choosing here) of Lion yet, but I want to know how accurate this claim is. IE, in older versions of OS X 10.1, 10.2, 10.3, 10.4, how much of the actual OS was previewed during the sneak-peak events. I suspect it is far more than less and that the major improvements in Lion are, fortunately or not, the main ones that were demoed already.
