You forgot:
Microsoft Forgets to Renew... = Yet another example of a top-heavy corporation unable to keep even simple things in check. Thank goodness Apple hasn't forgotten its user base.
Apple Forgets to Renew... = Calm down, people; non-issue. Do you even realize how much time a big company needs to address things like this?
Microsoft has 99,000 employees and it appears most of them are sitting around doing nothing at the retail stores.
Apple has 80,000 employees and they're working their asses off making the most profits per employee in the business world.
I heard the expired certificate error was because some Apple employee had to move all of his belongings to the new campus and he didn't get around the renewing it. Besides this certificate nonsense is practically a non-issue because Apple offers other ways to download system software.
In other words Microsoft should make less mistakes than Apple because they've got plenty more employees with free time to catch errors.
