I'm so much happier reading PDF files and the like now. Web pages, not so much. Getting a tablet has made me realize just how bad many of them are, and how poorly many webmasters and bloggers use their RSS feeds. No wonder services like instapaper and readbility are doing so well. Surprise casualty: Wikipedia. Needs a lot more work to be functional on a tablet.
The other thing is the multitouch functionality. My hobbies include drawing and electronic music and having a high resolution control panel is absolutely killer for these applications, in much the same way that the mouse was a huge game changer by freeing people from the command line.
I agree that responding to tweets, emails or forums and the like that don't require more than a few sentences is completely acceptable for me as well.
I am just saying, for me, its the one I would give up first, but I do currently choose to keep it.
I think we are saying the same thing, no?
I find my tablet (read iPad) is great for consuming content while laying around. I don't think they are quite as awkward to use as the author suggests, at least for me. However, I agree that at times when I want to be more productive it frustrates me and I always move to my laptop or desktop to actually get 'er done.
Another usage for me is that they are great for kids in the car.
I have a beefy desktop, 13" laptop, iPad2 and iPhone4. If you held a gun to my head and said I had to give one up I would, without hesitation, hand over the iPad.
