What an excellent and succinct summation, lloydt.
I'm one of those who loves his Reader, and wouldn't trade it. But I also can see that when the iLiad, or something like it, progresses a bit further, it could easily become something I would want for business/professional purposes. At the moment, I expect that the new TabletPC that I've gotten via work will fill my needs in that area. Since I can convert it to a slate, I can use it to take meeting notes without it being as obtrusive as regular notebook (plus MS OneNote is shaping up into a tool I'm going to love -- it might as well have been designed for the way I work, as nearly as I can tell), so I'm good for the moment, but down the road a bit, the iLiad 2.0 might be just the thing.
I appreciate you sharing your insights in the matter, you've helped me get a better grasp of my own thinking on the two devices, and, I think, offered those who are still trying to decide which way to go some excellent food for thought!
