My Notebook - Apple MacBook. I tried Sony Vaio, Samsung X15, Bliss, but is now focused on the apple computer and it has a number of rational reasons, specific to event-manager. 

  Making a presentation or conference, we are often confronted with the fact that our speakers are preparing presentations for Mac. And, these remarkable people do not think about the fact that event-managers who are preparing their performance in 97 out of 100 cases, work with the PC. They bring the stick and genuinely surprised if you have a Mac. You have not provided that opportunity? So you - not professional! We have provided, we are just those 2-3%. 

  Presentations made not only in PowerPoint, but in KeyNote, the program from the package iWorks. There, a greater choice for the animation of slides and transitions between them, the graphics get a clearer, easier to integrate video. Therefore, the speakers who work with KeyNote not think about how to translate the presentation in PowerPoint. 

  Another nuance - port to connect to the projector from another Mac, not VGA, as often happens, and DVI. It looks like (in older models)

or so (the newer)

 But the port for connecting to the projector looks like this:

This can be easily solved if you have an adapter. He stands a few tens of dollars and looks like this 

But if you're doing a conference in the seaside hotel in Turkey or in a cozy business center in Chelyabinsk? Find this adapter for 10 minutes or 5 hours would be easy, but if the adapter you already have. Therefore, we have it. As a spare Mac as a spare power supply.

And yet Mac looks good when you come to him for presentation to the client. An apple is lit on the notebook is very nice, and seduces the Client.
