I have been on the fence for getting an HTC Flyer, Acer Iconia or the Toshiba Thrive. I am currently typing this on my Gateway convertible tablet with Windows 7. I bought this tablet almost four years ago when I started paramedic school. I scanned all of my text books into PDF files and imported them into Windows OneNote. I used my tablet every day and took copious amounts of notes on it. The Windows platform (Vista at the time) along with a digitizing pen (non touch screen tablet) is just as fast as a paper and pen and far superior because of all the options in OneNote (and other programs). My "pen" also never dried out, my tip never needed sharpening or broke, and I actually was able to write faster than with actual pen and paper. You can highlight text, bookmark text, write down mathematical formulas and the computer solves them for you and tons more that I never used or figured out. You can import web pages or clips from web pages directly into your notes. So if we were talking about the heart I could browse the web for what we were talking about, find a picture or article I liked and import directly to my notes in one step and then add notes and arrows and such around the imported pic or text. The most awesome part, aside from having all my books in one place, was the search function. I could search for a word and it would find all instances of that word in every text book PDF and all of my hand writing. I have horrible hand writing and it always found the word or phrase I was searching for. This was invaluable when you have several hundred pages of hand written notes and you want to find something you wrote down about a certain drug or cellular structure.
I now mostly use my tablet as a regular laptop with the screen up and keyboard in the regular position. It is a 15.4" screen and fairly heavy since it is a full-on laptop with a swivel screen so it really isn't easy to put into portrait mode and read a book on my Kindle PC software or carry it around for web surfing and media viewing. It's served me well and will need to be replaced soon and I'm hoping that an Android tablet with a pen will eventually come close to the awesome experience I have had with this convertible tablet. I don't need it to do everything Windows does because I'm not in school anymore and I have different use needs now. However, based on my little bit of playing around with the Flyer at Best Buy, it is currently not even remotely close to the same level of pen function that a Windows tablet has. If you have a year or more of school left I would not hesitate to buy one of the few Windows tablets that are out there right now. They will be much lighter and easier to work with then my 3+ year-old convertible tablet but heavier, bigger and more expensive than any of the Android tablets out there. The trade off is that you will get a tablet that is meant for and built for a complete and awesome penning experience.
I really do wish the Flyer was as good of a penning tablet as my Gateway but it's not. Having a 10" option would also be nice for school situations but the 7" screen seems really nice for my current use needs. So I'm trying to decide on the Flyer which has great future potential if people develop more for it or a 10" option tablet (Acer/Toshiba) which have great connectivity options of full size USB, full sizeHDMI and SD Card (on Toshiba).
