Running this on the iPad Mini. I have 30+ books and it runs fine. I love the Dropbox import function and the ability to tilt horizontal for viewing 2 page spreads. Would like the option to import from services like Skydrive or Google Drive but I have a feeling that might be an API restriction or something. Overall the best app Ive used for reading .cbr/.cbz files on iPad.
