The objective of a technology sales presentation is to convince your potential client of how great your product is, and how poor the competition.

Assumption: the above is actually true, which makes designing a presentation a lot easier.

One approach is to list all the benefits, and in a few more charts show that the competition does not have them (most of the times, without naming names explicitly). This story does not stick very well, a feature list that seem unrelated.

Better is to dive in a bit into the detail. Often technical products have one specific innovation, one characteristic of the architecture, one design approach that triggers all of the goodness mentioned above. Now that the customer understands this (and Einstein said that you can explain anything to everyone - even a 6 year old), it becomes a lot easier for her to understand the full picture.
