c) You can show Keynote presentation from an iPad while using an iPhone as remote control. .
Folks - I get it. Use an iPhone. I hear you loud and clear. But I'm rather invested in the Android infrastructure.
For any other device - including a Macbook - you can use a bluetooth or USB remote presentation clicker. The only workaround alternative to this for an iPad is the universal call "Get an iPhone (which is a $900 solution to a $50 problem) or using a bluetooth remote in something called "accessibility mode."
Is that it? Are those my only alternatives?
(And LOL at the poster suggesting I go to Microsoft. Have you used Keynote?)
