I also have iMac and Macbook pro. But after I bought iPad, the chance to turn on my iMac becomes less and less. Sure, my iPad changes my "reading" style, U should try it. However, it's still heavy for me to hold iPad for reading all day long, even only 700g. At this time, the H4 holder helps me a lot to prevent carpel tunnel syndrome.
