Has anyone had the chance to work extensively with the Mantis and the new Brailliants? Which one do you prefer for productivity connected to Mac or iPad or both and why? If you use braille with speech completely turned off, is it awkward to quickly navigate and quickly check the display?
I've used neither, but I am planning to by a Brailliant. The main difference between the two is the fact that the Brailliant has a perkins style while the Mantis has a QWERTY keyboard and is cheaper, at least in the U.S. The brailliant is also temporarily out of stock. From looking at the description, there seems to be little difference in terms of productivity. The Perkins versis QWERTY difference would, I think, be the first point of consideration. Below are some reviews, and I am sorry if I've repeated anything you know already.
For the brailliant.
