No ad here, just a crazy happy user of Splashtop Remote Desktop. You install the Splashtop Streamer program on your Mac or PC computer, and the appropriate app (iOS, Android, webOS, Mac/Windows, Kindle Fire, Nook, BB Playbook...) on your phone or tablet that is WiFi enabled. The Streamer running on your desktop will give your mobile device full access to your entire desktop. It's very cool and works great.
You do not have to be directly connected to the same network, either. On my HP webOS TouchPad and a WiFi connection anywhere, including the WiFi Hotspot app on my phone, my TouchPad finds my dssktop by registering thru Google. Then I'm off, running SUDS directly, with full control, on the TouchPad from my deck, or a buddy's house miles away.
