Holy crap I want one of these so I can take it on the train with me every single day. In fact, I want to take it everywhere I go all the time.
I freaking hate them all. My friend Ivey calls me from the road when she's on her way over, and she always starts a whole conversation. I'm like you're going to BE HERE in 20 minutes! To hang out and chat with me! Why are you having a phone conversation in preparation to hanging out? I hate phones.
