Sorry to be so blunt, but wtf is the big deal if I have to download it myself?
As a SysAdmin, I actually much prefer that systems don't come with Flash pre-installed. First off it is a security hazard; it seems like the Windows version has an update every other week. Secondly, there are absolutely scenarios where I wouldn't want Flash on my system - this saves me the step of disabling it before locking down the system and deploying it. Third, if you install Windows XP *gasp* you have to go download the latest version of Flash. I haven't bothered to check to see if this is the case with Windows 7, so I won't comment on that.
I much prefer to install only the software I want vs. having a bunch of 3rd party junkg pre-installed.
