Err, I hate to break it to you, but this has -one- microswitch, as well as a plain old optical chopper pair. nothing special about either of those. as far as "significant R&D and engineering" goes, capacitive tech has been around for ages, a simple array of sensors isn't anything novel.
There really isn't anything in this that justifies the ridiculous price tag.
Yes sure it "isn't anything novel" that's why no one has a product like this out yet...nothing novel...
go buy yourself one of those fugly prototypes by microsoft sitting on some loser bozo's staffer's desk instead.
