Hi Everybody, I am thinking of buying 2 tablets. I have PowerBook G4. Goal : find some cheap solution to exchange notes while on skype. Recently one of our collaborator moved to different state. Skype is really great for all conference call meeting .... but problem arises when we have to exchange math formulas. There is no easy way to write them easily and exchange on skype ... so I thought may be tablet is the answer. So I am looking for some cheap solution .. so I can buy two of them and send one to my collaborator as well. Any ideas and advice will be helpful. My apologies if this is wrong place to post this kind of question.
