Tech in the Classroom

So as a graduation present to myself I bought a brand new iPad. I'm already addicted to it, whether it's checking my email, playing some mindless game, or reading using the iBooks app. I absolutely love it. Now, as I'm researching and looking into things for next year I'm coming across a lot of bloggers/websites, that talk about using the iPad in the classroom.

I recently downloaded the TeacherPal app which works as a class roster, seat arranger, and grade book app. I'm anxious to use it in real life though haha.

Have you lovely ladies used any fun gadgets in the classroom? If so, what were they and how did they work?
