iPhone as a study tool

I read a lot and am forever coming across words or concepts with which I am unfamiliar. The problem used to be that I rarely read where my laptop was and used to have to keep writing down words or concepts on paper to check them next time I was at my computer.

Now, due to the amazing and seductive ease of my iPhone as a web browsing tool, I am able to use it to check things in the wikipedia and dictionary.com as and when I come across them. The result is that I check things far more often and because it is at the time, and in context, I am much more likely to remember any new concepts or meanings.
