Thanks for all the replies, they are going to be very helpful in "critically analysing"
the different elements of these terminals and I'll be taking different quotes from these threads to comment on how the different designs have different advantages and disadvantages over each other. Now I must go bash my head against a wall for a few days as I try to fill the assignment criteria....
Again, its greatly appreciated, my lecturer should accept comments made on this forum as being more credible compared to the crappy review sites you find over the internet.
