My iPad is my college companion. I use it to replace notebooks and take handwritten notes digitally instead now.
Evelyn, that was a great rundown on what you use the iPad for. You are making good use of the technology. And having been a Physics najor in my college career, I know what you meant about the price and heft of a science textbook. Oh, if only we had iPad back in the day.
I use my iPad for notetaking in meetings. May I ask what notetaking apps you like best. (I will check over on the thread about the "best notetaking apps", just to see if you have posted there, also.
