I already have an iPhone 4 and a Macbook Pro 13, should I get an iPad 2?

I'm currently a student studying computer science in a local university. What I think is that iPad is good for taking notes during lectures. However, during tutorials I have to stick with my macbook for the faster typing on the proper keyboard and faster processor. Not to mention that macbook would be a better choice for for lab lessons.

I'm kind of confused right now. IPad 2 does have it's advantages and disadvantages. Hope to hear some feedbacks and advices from you guys.

Is it bad for an iPhone to get too cold?

I was detasseling and someone went through my stuff on the bus. They took some food out of my cooler and I'm assuming they didn't steal my phone because it was locked. When I got back on the bus my phone was in the cooler. I DID NOT LEAVE IT THERE. There was a good amount of condensation when I took it out. And it was really cold. I'm worried about the quality of the cameras and speakers. & probably te screen too. Do you think anything will happen to it? Should i maybe put it in rice or something?
