I deliver a lot of workshops throughout the year. When I decided to work on presentations and workshops as a full time career I purchased a laptop and an LCD projector. These were the best idea for me, I learned a lot about how to use the equipment and practised in my own time. I was able to get better at the set-up so I could prepare my presentation. 
It helps to have a son who is proficient at computers because he spent time explaining things to me and he displayed outstanding patient at some of my questions. I laugh now when I think about some things I asked him about computers!!
Anyways, I try to keep a look out for accessories that would make my life easier, especially for the equipment part of it. I was at Chapters one evening and I found this item called the Hubman. It was even on sale!
This Hubman has four USB ports and a 5V outlet plug.
I used it when I did an ASIST in High Prairie and it worked great. I was able to put all the equipment together in a convenient way without it looking all messed up.
 

Isn't it cute, when it is in use the green light comes over where the heart is located.

Here it is when I am using all the ports. A month later and so far it's been great. 
Two thumbs up!
