Enjoying the episode! I've wanted to get a Kobo for a while but somehow ended up with a few Kindles instead.  

Anyway you might check out the KOReader (Kindle / Kobo Open Reader). I've been using it on my jailbroken Kindle to read epubs. It doesn't pay attention to Metadata at all, it just has a file browser like it appears you prefer. It actually took me a while to get used to this because I'm more used to being able to sort and search by Metadata. Look for my show on the KOReader next week...
