The review is rather vague isnt it?
What matters most is the quality of the keys, the layout can always be changed thru binds. I like the concept of the zboard but I'm worried the key quality is no better than a normal keyboard - and I think 99% of keyboards are crap worth only the $20 you pay for them.
I'd pay $200 for a really good keyboard with keys that *always* respond. Pity you cant seem to buy them.
