Reading on the iPad is one thing, but what about writing, or spreadsheets, or giving presentations?
Jeff Smykil at Ars Technica has a great, comprehensive review of iWork, the productivity suite for the iPad. I’m personally not inclined to shell out the money for these applications; I have a perfectly serviceable desktop and laptop and don’t foresee any need for heavy-duty writing, spreadsheet-using, or presentation-making on a device without a physical keyboard—and they’re only orthogonally related to e-book-reading anyway—so I doubt I’ll be reviewing them myself.
Smykil finds that, while the suite is about as good as such a thing can be on the iPad, the form factor of the iPad is really not best suited to that kind of work. See the review for more details.
