The folks at Skype (now a part of Microsoft) recently launched an Android tablet version of their ubiquitous voice/video chat app. The tablet's larger display is well-suited to video chatting, particularly for conference calls with multiple participants. The beauty of Skype is its platform-agnostic design, as well as the bottom-line benefit that Skype-to- Skype video and voice calls are free over 3G and Wi-Fi. Indeed, the Skype app is a must-have for Android tablet owners. Skype users running Android 2.3 or newer can access both front- and rear-facing cameras -- assuming they have both -- but those stuck with (shudder) Android 2.2 or older can only access the tablet's rear camera.
