Just to shift gears a moment: one new "special" app I've been getting a lot of mileage out of over the past year is something called Outline 4D
published by Write Brothers Inc.
This truly is an outliner/brainstorming app "on steroids." (As their sales literature so aptly puts it.
Ostensibly designed for writers and writing projects, but I've also used it for website information design, project planning, and general creative tasks.
Not inexpensive by any stretch. But if it's the type of app you can see a use for, it's well worth checking out. I have yet to see anything equivalent that does half as much half as easily. Publisher List: $99 (Street: $89/box-$79/download.) Occasionally goes on sale at various seller sites so be sure to shop around before purchasing. (Don't let the garish colors throw you. You can change them to anything you want.)
Note: This is one of those apps that you have to experience before you can grok
all it can do for you. And it's also expensive and specialized
enough that you had best try it out before you key in your credit card info. There's a 5-day trial copy download available here
