I found the London International Technology Show to be a huge disappointment.
It occupied a fraction of the space that the publicity had implied, and the number and range of stalls was also very limited.
Had I been a game player I might have been more positive, as stalls offering gaming equipment had systems set up to demonstrate their use, but even those were problematic given the queues to use them.
The one major bright spot was the stall showing a powered exoskeleton which allowed their demonstrator, a woman paralysed below the waist by a skiing accident, to get out of her wheelchair and walk.
Unless the organisers (Dennis Publishing) manage to attract far more companies to to take stalls, I would not recommend this event to anyone.
Overall: A waste of time.
