I am starting to see the quality of the Android port apps showing up in App World increasing steadily. The latest gem is a Remote Desktop Protocol (RDP) Windows Client (Aka Terminal Services client) for the BlackBerry PlayBook. It runs in the Android Player so you will need to be running PlayBook OS 2.0. This app by Forseti Digital is going head to head with a native RDP client for the BlackBerry PlayBook that was released recently for $6.99. Either way its nice to have options and competition!
You can find Forseti RDP Terminal Service Windows Client for the BlackBerry PlayBook in App World for $8.99. They also have some good documentation for the app here.
