This is a great review video for some one who looking for the difference between this three leading e-book reader.
For the wireless book buying : In my opinion I think the touchscreen in Nook and Sony daily edition are great – very easy to use. While with Kindle it seems a little bit harder to control. and the mini color screen of Nook is very tempting ! Even it is not for reading, But I think this color screen make the online purchase look more easier.
For the reading : I think Kindle and Sony daily edition faster than Nook on books loading. But as you see, The Sony daily edition has a great big screen (In this review video is Kindle 2 not a DX). See it yourself and please tell me what do you think ?
