Having given this app a spin and having spent the registration fee, I'm regretting doing so. Overall, the app isn't bad but it really isn't worth any kind of "2.0" moniker. It's close to a 1.0, but it's still missing features I have a hard time imagining missing from a first release. At first, I thought I could do without them, but at this point, this app will just sit in my application folder without being used ever again.

Downsides I'm seeing:

• Connecting to the internet to get covers and data is nice, but since you're using an incomplete volunteer-based system, there is a lot missing. Not just obscure stuff - twenty or so issues of Grant Morrison's New X-Men run, for example.
• Adding stuff is painful. Where is a batch add? where is a batch 'download these issues from the internet' option? i have a long list of books I have, I really don't want to enter them one by one.
• If there's ever been an app that could benefit from copying the itunes interface, it's this one. As it is, it's hard to find things and it's hard to view things in a series context. how about at least a folder system, or a click arrow to expand style subelement system?
