Just got to thinking about reading on the computer, which is what I used to do years ago with my PC (yBook, from Spacejock

)
I had downloaded a reader,
Kitabu, some time ago, and just now opened it again, and I really like it. I've just visited the dev site in order to get the link for everyone who may want to try it, and discovered that there are a few other epub tools there as well. Might be worth a look for those who need to convert, edit, etc
Also noticed that they say Kitabu is going to be part of a cloud based service. I haven't heard anything about that, but if they create an iOS reader and a cloud base, it could be what we are all looking for
Kitabu is on the Mac App store.
