How can I look more "hi-tech" with Apple devices in a presentation?

I will do a VERY IMPORTANT presentation to a company. I will sell my products and the result of this can, literally, change my life.

So, I was thinking: how can I cause a really good impress using some smart ideas?

Maybe they never used Apple devices. So everything can be new for they and I want to use it in my benefit.

The hardwares I have now is (some is mine, anothers I can get with friends)

• An old MacBook with Mac OS X Lion.


• A Mac Mini with OS X Yosemite and a common monitor (not apple one)


• An iPhone 4S


• An iPad 2


• An iPad 4th generation


• An Apple TV (2nd generation I think)


• An Apple remote Control

My idea is use my MacBook and connect it in some video projector. I have cables for VGA and DVI, so this will not be a problem. I really don't know how will be the place I will show, but I really think this will be a "Microsoft Windows World".

Only with this hardware, what I can do? How can I look more "cool" or "hi-tech"? This is some ideas:

• Use my iPhone like a remote mouse


• Use the iPads like a secondary and live screen


• Broadcast files with a wireless connection

Maybe I can't buy more hardwares, but I can easly buy softwares if necessary.

Any good idea?
