iBooks app has just landed at the App Store. Proudly proclaimed as being "designed exclusively for the iPad," this app gives you direct access to the iBookstore, which will offer free samples of books ahead of purchase and a brand new way for you to channel money into Cupertino pockets. Built-in search, highlighting and bookmarking features are augmented by text-to-speech functionality and ePub format support. Funnily enough, iBooks will only support DRM-free ePub files sourced from outside the iBookstore, but no mention is made as to whether its own wares will be similarly unimpeded. Speaking of restrictions, the whole operation is still limited to the United States, leaving the Stephen Frys of this world sighing wistfully from across the pond.
