Aside from being cross-platform, Qik Video Connect offers several other nice features, like video mail. If you can't connect live with someone and you just have to show them something, then video mail is the only way to go, right? This feature is free until June, but after that you'll have to pan an "optional fee" in order to use it.
Qik Video Connect also allows you to share your videos through various social networking mediums - Twitter, Facebook, Youtube, etc. That doesn't require a front facing cam, either - you can just share whatever is going on around you quickly and easily.
If you're still not sold, here's a video (complete with creepy translucent hand) that highlights some of Qik's features:
One thing worth noting, however, is that Qik Video Connect does not yet support any Honeycomb devices, so if you had hopes of improving your tablet's video chat capabilities, you're out of luck.
Qik Video Connect is available for free from the Android Market, and supports Android 2.1+ on 3G, 4G, or WiFi. Grab it from the widget below.
