I was wondering if anyone can give me some feedback. I was thinking it would be good for my son to use at school. Sometimes he wants a last minute meeting with a teacher or study time with friends. He often uses his text screen on his phone for this but the teachers are not good at texting and resort to paper. This would allow for real time conversation. One feature I like is he can later download the conversations to his computer. One drawback is it weighs six pounds. Any thoughts?
