Yes, there now exists a giant (55 to 84 inch diagonal) Android Tablet! The Clevertouch Plus is an Interactive panel which comes with an on-board Android processor.
The board also comes with software for your computer: CleverLynx, CleverMaths, DisplayNote and Snowflake. The first two are IWB authoring packages ...you will find more information and resources on my other website at http://www.cbiproject.net/lynx.html; DisplayNote is for remote control of the interactive panel; SnowFlake is another impressive IWB/assessment package (however, I have found that is resource demanding)
The Clevertouch Plus is available from, among others, Toomey AV in Baldonnell ...visit http://www.toomeyav.ie/
