Thanks for the very lukewarm acknowledgement, at least.
Seriously though, product cycles are very long in the industry - and Jobs was there before his first leave for the major decisions for most of the products that the public saw during the first "Cook era".
Look at where we are today. Although people wonder about what products using Sandy Bridge will come this spring/summer from Apple - the reality is that Foxconn is working on manufacturing the Sandy Bridge systems and the teams at Apple have already moved on to working on Ivy Bridge systems. And "Ivy Bridge" is public knowledge - Apple partners under NDA have access to things after "Ivy Bridge" (or at least much better information about Ivy Bridge schedules and capabilities (server/desktop/mobile, dual/quad/hex core, chipsets, ...)).
So, anyway, claiming that "Apple did OK during the few months that Cook previously was acting CEO" is missing both that Jobs was in fact in touch during most of that leave and the fact that major decisions on many projects that the public saw during the leave had been made months before Jobs' leave.
And claiming that Jobs is the single cause of all of that is missing the fact that Jon Ive, Phil Schiller, Tim Cook and all the rest are all talented at what they do. Really, they're ALL important.
