i read on my ipad several hours everyday. Half of that is surfing the web or reading news on instapaper, and half is reading ebooks. I've never owned a dedicated ereader device like the nook or the kindle. I suppose they are lighter, but they are another device to carry, and for me, carrying around a device just to read books doesn't make sense, when i can take an ipad and have a choice to read books, watch videos, or play games, whatever i'm in the mood for.
