If something is not normally done then does it mean that it shall never be done in future as well? For the last six months, meetings in our office went totally wireless.
We installed a new “wireless presentation systems” called Zoapi Hubs, for our meeting rooms. Now people just walk in (without cable adaptors), open their mac/win top & share their screen over WiFi in less than 30 Sec. Believe me, Mac Airbook users just love it. These “Zoapi Hubs” also allowed multiple presenters & switching between presenters with Zero Overhead.
