Google has launched an ebooks category in Android Market, but in the US only for now. Books can be browsed on the web version of Android Market, then wirelessly sent to phones.
It's more surprising that it took this long than that Amazon's reader app is coming to Google's mobile OS.
Text search, orientation lock, annotations, Wikipedia integration--all real improvements. So why am I still cranky about Kindle on Android?
After a few months, Google's mobile-phone operating system won me over with a powerful new generation of phones.
