I'm posting this from Google's Blogger widget. I'm posting from my personal 12" PowerBook.
I love Apple's Dashboard. It creates an excellent mental separation from what I'm doing and what I'm trying to keep track of, and helps me check out what I want to check out. What I hate, however, is that I have such limited real estate on my small monitor, and I always have to shift widgets around and close some if I want to track a couple flights or monitor another ski resort. They need an auto-arrange feature for Dashboard that tries to keep things about how the user had them, but lays things out so everything's visible.
In posting this, I realize that the Blogger posting widget isn't great - it expands every time I type a new line, instead of having a scroll bar. Now that's annoying.
