I can't access the Android Market and confirm this, but everyone is reporting that Kobo released their Android app today. This means Kobo now supports the most platforms than anyone. See, this is why I said they are the only serious threat to Amazon.
Can someone do me a favor and grab a copy of the installation file? I'd like to try it on an Android tablet. Thanks.
Update: Kobo just announced on their blog that the Kobo ereader will be getting a firmware update sometime after 28 June:
Here is a sampling of some of the improvements we are making:
1. ePub Font resizing.
2. Hiding 100 Free eBooks.
3. The “Off” Screen.
4. Sleep Mode.
5. Low Battery.
