I was very much against the iPad after seeing the Apple Event (mainly because of multi tasking), but after a few days of thinking about it. I have changed my tune. This blog I think is the best writeup I have seen on what the iPad really is, and what it means to the future of computing.

This is the part of the blog that I really loved:
"The tech industry will be in paroxysms of future shock for some time to come. Many will cling to their January-26th notions of what it takes to get "real work" done; cling to the idea that the computer-based part of it is the "real work".
It's not. The Real Work is not formatting the margins, installing the printer driver, uploading the document, finishing the PowerPoint slides, running the software update or reinstalling the OS.
The Real Work is teaching the child, healing the patient, selling the house, logging the road defects, fixing the car at the roadside, capturing the table's order, designing the house and organising the party.
Think of the millions of hours of human effort spent on preventing and recovering from the problems caused by completely open computer systems. Think of the lengths that people have gone to in order to acquire skills that are orthogonal to their core interests and their job, just so they can get their job done."
