Ipad Bluetooth Keyboard or Samsung Chromebook for school?

I currently own an iPad 2 and will upgrade to a mini or larger one when the new ones are released. I also own a laptop which I upgraded to Windows 8 and love it. I am looking for a portable machine to take to school for taking notes, web surfing and video watching via external usb drive. I love the portability, price and focused experience of the Samsung Chromebook ($249). I could go the cheaper route and get the Logitech Ultrathin Keyboard ($80) and take my iPad to school. The keyboard is not as good as the Chromebook and would be about the same weight when combined together. Keep in mind that I am jot looking for a laptop replacement and I own ipad notetaking apps (Pages, 1A Writer). Does anyone have any experience with either one in a similar usage case?
