I agree it is an interesting piece of technology.
I think that in about 1-2 years time, there will be quite an array of equipment from different supliers which means:- 1. choice, 2. possible price reduction and 3. each manufacturer will come at the same technology but with their particular slant which should make it more interesting.
Having recently seen the new Kodak digital camera with the huge Organic LCD on it's rear panel and compared it directly with my own and others. It wins hands down on the ability for the human eye to see at acute angles, also, and I don't know why, it appears far clearer and easier to read.
When this technology is married to a waterproof GPS system, then that's when I think I'll start to seriously think about getting one. Until then, they are not on my shopping basket list.
