I am going to university in September and I really don't want to keep all of my notes on paper anymore since my notes usually end up completely disorganized. I was originally planning on just using my laptop but I am in engineering and it will be impossible to type out equations. Would a tablet and stylus suffice for for just writing down equations with no sentences? I also want the table for some media usage so I would prefer something like the Galaxy Tab 10.1 or Asus Epad. The HTC Flyer looks like it has good pen functionality but I don't really want a 7 inch tablet.
