I'm going to call it ipaditist...

I bought the last two robert jordan books and have been enjoying them on my ipad, reading on the bus kills time more cost effectively than watching a movie when you get right down to it, but I noticed that my shoulder was hurting...

I finally put two and two together and confirmed it today while watching a video, if I sit holding my ipad in my hand while watching or reading, I end up with a very sore shoulder within 30 minutes that can last for days... Wonder if anyone else has this ailment, kindle, ipad, whatever..
