I don’t think any amount of showmanship would make Google product and service announcements as interesting and impactful as Apple’s.

One problem is that Google doesn’t stick with or commit to most things, except Search and e-mail. So Google products just aren’t that interesting.

Another is time to release. Apple doesn’t generally announce things (with a few exceptions) unless they are close to release. It’s no fun to get excited about something and then wait a year or two.
