Oh, this is the "mature" attitude to take? Gotcha.
Some of us have concerns beyond our own wants. Some of us are concerned for the platform and are tired of seeing uncoordinated event after uncoordinated event kneecapping the launch buzz and potential of a platform we really, personally believe in.
It's not a temper tantrum to note when Microsoft fails to execute successfully. Yesterday was a failed "event" due to little new information and even fewer launch specifics. They don't have a lot of luxury to make execution mistakes with Windows Phone 8, in case you haven't noticed.
People DO care. Any time you leave potential customers waiting, there is a very good chance that they lose patience and simply walk out of your restaurant...or your grocery store....or in this case, they simply renew their contract with yet another Android or iPhone. The successful businessperson puts as few obstacles as possible between their customers and their product.
In Apple's case, you simply tune into an event or read the widespread coverage of it afterward, and you know all of the details and can get the thing they have you so excited for in a handful of days.
In this case, you tune into, what, the fourth Windows Phone 8 related event, see Jessica Alba shill for her site, watch some kids get silly onstage, and hear that the games you don't play anymore (Words With Friends, Draw Something, Angry Birds Space) on iPhone or Android are "coming soon" to this new platform. And here are some awesome new devices that are coming "in December" or "by Thanksgiving" or "TBA".
If you can't see why we're scratching our heads and voicing our displeasure, I don't know what to tell you.
