Playing catchup, are we? Sony's hot on the trail of Amazon and Barnes and Noble, who already have e-reading apps for the Android
platforms, with its own freshly announced Reader offering set for release next month. The functionality in this upcoming slice of software will be familiar: you get to access books already purchased at the Reader Store
or pony up cash for new ones, while making bookmarks, notes and highlights on your mobile device. Throw in adjustable fonts and you've got your boilerplate beginning to a decent mobile e-reader. Now you just need to pick your fave ebook purveyor.
