In august I did hear the first time about Marvin; visited the website and directly wanted to use it. Si I did go to app store and then the first disappointment was there: only for Ipad and I only have a Ipod thouh and so ibook will stay my reader.
But then came the message that Marvin will come to iphone/Ipod thouh; so I waited till today when I firstly heard it was available on app store. Second time I was disappointed when entering the app store because I had to pay while ipad users have it for free. Why that difference. It may be a very good reader and even be worth much more then the price asked but I have no possibility to check that out for my self.
Gonna have to think I stay with ibook (and always asking my self if marvin would be beter for me) or pay for something I have not (yet) the feeling that I want marvin (even with all screenshots and descriptions ans good user reviews).
Hope to be surprised about this in the future...
