Then you cannot do that at a show organised specifically for the purpose of showing off Pegasos kit or Amiga kit. This would have to happen at a more unversal appeal event.
Publicity cannot be beaten on one drum, if the products aren't there to sell in the volumes required and the reviews aren't out there and are positive enough to justify it you might as well stay under the radar and get people in on word of mouth else you will fall on your arse.
Where did YOU first hear about a new computer? At a trade show? At a show organised for that computer? As a feature in a magazine? On TV? On "Digitiser"? Word of mouth?
Be realistic. The only people attending will be a self selecting group of people - those that are interested in the product in the first place.
Not saying don't do it, just be realistic with your expectations.
