Hi all. We just released a new version of System Manager and Launcher with new network features. If your P3 is network-connected (using the built-in WiFi adapter - no additional cost), Launcher and System Manager will both identify new apps and new updates, and System Manager will give you the option to install them over the network.
There are a number of other features that make sending logs and installing your own apps a breeze as well.
You'll need to install this new System Manager (184.108.40.206) via USB, but after that you can stop buying new USB drives every time you misplace one.
