Well, I have to say I am somewhat surprised by some of the replies.
I have purchased and used many gadgets in the past, and a significant part of them I never used stock: as soon as I got them I hacked them, replaced their firmware or modified them in some other way - as they better suited me that way.
The Kobo in its current version looks like it has decent hardware - but the software on it is useless for me. I have several thousand ebooks - and without having some way to group them I cannot use them on the Kobo. So I will really not use it before I can somehow fix this major weakness.
One way to fix it is to use another firmware written for the same hardware - that is what I will try first.
Asking if someone else is considering this - what is wrong about that?
I asked an honest question - sorry if some people got offended...
