Mini 10 is ok as long as you can get by with a VGA out- it lacks a DVI/HDMI out. It can do the actual job of making slides if you buy Office with it.
I am assuming you mean make the slides then present them with a projector. If you want to show people the slides on the machine then I hope it is for a sharp shooter convention because a 10 inch screen is really small.
It's to hook up to a projector. At my office, someone had the idea to get these desktop replacement things that weigh like 10 pounds. It's ridiculous.
