Today's "big" announcement by Apple just ended--new versions of the iPod Nano and Touch, and a new version of iTunes, plus some new headphones and a lot of chest beating about the App Store. Almost everything had been leaked weeks ahead of the presentation, and even if Apple had kept a lid on it all, there would have been nothing all that exciting.
The new pricing for the iPod touch isn't going to drive sales (if you're even mildly interested in the 3G iPhone, you're crazy not to buy one of those rather than an iPod Touch.) The revisions of the iPod Nano are nice, but no one is going to be lining up to buy one; at best, it'll be a good replacement for previous-generation Nanos. Apple seems to think that the new "Genius" feature in iTunes (a ripoff of Pandora) is going to generate more sales, but I disagree.
The net of all of this is somewhere between "feh" and "so?". Any other company would have made these announcements with a press release, and perhaps, a press conference. With an announcement like this one, the very fact that Jobs was involved actually increases the disappointment level.
The last really important announcement that Apple did was the original iPhone; compared to that one, today's announcement doesn't even merit a footnote.
