I justified my purchase of an iPad3 "for business" and discovered it to be the most fun & useful toy I own (motorcycle excepted).
I'm in the process of identifying and loading useful apps and hoping that Bill Gates will release an Office app soon.
With the availibility of Kindle and Nook apps, my e-reader is sitting on the shelf. With the iPad, I can also borrow e-books from my local library.
I will probably have some app-specific questions, and will rely on someone's expertise to help.
