Stacks was crippled. Resolution independence didn't come to realization.Sure... cameras and barcode scanners are revolutionary... for the 80's that is. Vista is crap. Apple can actually deliver new OS updates in a reasonable amount of time. Microsoft had to return to the drawing board several times before Vista even saw the light of day. I didn't mind Leopard being delayed. At least Apple stated the reason and then delivered Leopard instead of stalling again. As far as crippling features, I haven't noticed any. I run high end apps in Leopard every day.
Microsoft stated the reason Vista was delayed, and then delivered it. Apple stated the reason Leopard was delayed, and then delivered it. Both Vista and Leopard were delayed more than once, with features dropped.
Vista being crap is your opinion, and has no bearing on actual comparisons between the two products. OS X was crap up until 10.3. (Ooh, controversial statement right there.)
