Own an iPad or iPhone?  We’ve just published a couple of our developer resources in EPUB format, so if you just pop along to the iBookstore (open iBooks, hit Store) you’ll find ’em there:

• The Visualforce Workbook
• The Chatter Workbook
• The Force.com Workbook
• The Force.com Fundamentals book

Let us know how easy you find these to read – or if it’s useful to have them in this format.  Reading them on the iPad is particularly gorgeous!
