Readdle has released an iPad-optimized version of ReaddleDocs. The new app features an interface redesigned for the iPad's larger screen, along with a PDF viewer, an e-mail browser and a built-in text editor. Users can connect to a range of online services, such as iDisk, Dropbox, or Google Docs, and download files for offline viewing. The utility also allows users to save e-mail attachments and some other files found online. ReaddleDocs is a $5 App Store download.
