I`ve had a be-book for about 6 months now and I`m still happy with it. I`ve not updated to the latest firmware because I prefer my books in the mobi format and the latest update won`t read book in the secure mobi format (I don`t know if it will read not DRM mobi but it probably does).
I prefer mobi format because I think the layout looks nicer on the screen, the zoom function in epub doesn`t look as good to me as mobi.
I`m not sure what firmware yours has come with, perhaps they`re shipping them now with the latest firmware already installed.
One thing that attracted me to the be-book was the amount of formats it can read so I guess the best thing for you is to get free books in the different formats to test which you like, using calibre which is free and very easy to use you can convert books to various formats to try.
Pdf aren`t very goo on the be-book as you have to zoom in all the way to read and then it`s not very big.
I am still very much a newbie when it comes to ebooks and readers but I`m learning all the time, keep at it and just experiment, there`s always the reset button
