Google formally launched its tablet-optimised operating system, Android 3.0 AKA Honeycomb, at an event in Googleplex that saw the guest appearance of American singer, rapper, songwriter, and record producer Cee-Lo.
Honeycomb is specifically designed for large screen devices like tablets although it is unlikely that Google will introduce any specific measures to prevent manufacturers to use the OS on desktops, smartphones or laptops.
Amongst the main features that differentiates it from the normal Android flavour are the new System bar, which is not unlike what you have on Windows; it is always present and appears at the bottom of the tablet's screen.
The system bar has a "lights out mode" that dims the bar for full-screen viewing and comes handy as the bar is always present; at the top of the screen is the Action bar which is application specific, just like on Windows and is always visible whenever an application is active.
Honeycomb also has customisable home screens, a redesigned keyboard, improved text selection, copy and paste capabilities as well as new connectivity options. Some of these like copy and paste have already been implemented in Android 2.3. The 53 minutes video of the event can be streamed below.
