i had the opposite experience. I had a a laptop and liked it OK, but I was getting sick of the screen wastage - I read a great deal of material in PDF and long article form, and I'm sick to death of web design getting in the way. On 80%+ of the websites I frequent, 30-40% of the screen is empty, with acres of blank space to each side. I was getting to the point of wanting to turn the laptop on its side so I could have something with the same aspect ratio as a printed page. There's a limit to the amount of text I can read on a smartphone without eyestrain but I can work on a tablet for hours in comfort. The keyboard works OK for me; I wouldn't want to write a novel on it but it's fine for notes and short comments like this (the on-screen keyboard, that is...I prefer a plugin one for long-form writing).
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.
