Barry Kaplan:

"Firstly, literally EVERYONE involved in spatial computing should read this article. Is there an award for best piece of business journalism for the year? Because if there is, this article should be a finalist, if not the gold medalist. Avi Greengart has ABSOLUTELY nailed it! Secondly, thanks for the mention Avi. Before I got to the part where you mentioned “Wearable Devices”, this was already a terrific article. To be mentioned as a viable input solution alternative is an honor."
