The iPad bashing is a little much. I use it heavily in undergrad note taking, it's more about finding the app with the features you need.
I bluetooth sync my ipad to a keyboard, open my app and start taking notes, as I take notes the ipad records the entire lecture's audio, and correlates it to the words I'm typing. When reviewing, if my typed notes are vague, I tap on the word, and it instantly plays the audio of what the teacher was saying as I typed it. When extensive board diagrams are used, I pick the thing up, hit one button and snap a pic of the board, which is automatically imported into my notes. When I'm done, I have perfectly formatted notes, including audio of every lecture, links to relevant web pages, snapshots of the board, and links to any videos shown in class. All done in real time, with no editing or assembling of this data after class. Every night the thing auto connects to my wifi at home and uploads all of the files including the master file that has everything formatted to it's respective folder on my computer. It has a pretty awesome auto-eq system that cuts the general classroom noise out, and gives you very clear audio of the lectures
Oh, and it weighs like an ounce, fits in a small draw string bag, and stays charged for 15 hours. I also have all of my text books as E books to reference on it.
This is actually pretty impressive. I'd like to think that I'd actually make use of this level of quality notes, but time will tell.
I've really been interested in picking up one of the Asus Transformer (pad or prime), but I have a hard time rationalizing springing for a new notebook/tablet/netbook while my MacBook is still running strong.
