I forgot to post this when I got the notification, but Humble Bundle 3 for Android (also supports Windows, Mac OS X and Linux) is now available.
http://www.humblebundle.com/The bundle features BIT.TRIP BEAT, Fieldrunners, SpaceChem, and Uplink. The bonus game is Spirits if you beats the average price, which currently sits at $6.41.
Four addiitional games (Anomaly: Warzone Earth, EDGE, Osmos, and World of Goo) have been added to the bundle in the last few days making this very good value for money.
You can tweak the percentage of your money that goes to the devs, charity and running of the site. The games should work on your computers as well as your tablet/smartphone.
