I'm one of them. But it's usually to check flight status, make notes, check the calendar or weather or something along those lines. All of that functionality is probably going to end up in the Today view, making it a pretty obvious replacement for the dashboard in my usage patterns.
The Today view can't replace all the Dashboard use cases. For instance, on my Dashboard I have:
* Weather
* Stocks
* iStat Pro
* Dictionary
* World Clocks
* Astronomy Pic of the Day
* Calendar
iStat, Dictionary, APOD, and to an extent World Clocks can't be easily put into small widgets housed within a vertical stripe. iStat takes up half the page vertically, Dictionary's definitions would be cramped/scrolling, APOD is too wide, and having a large number of World Clocks would be unwieldy. I mean, yes, you could find solutions for all those, but they wouldn't result in great user experiences.
I hit F19 and instantly I have all that right in front of me. I have no interest in the Today View, as it's not even useful on iOS. Though that has more to do with the UX and design than the concept itself.
