I think it's a great machine. Folks that don't already have a Gen 1/2 will love it. It's not an iphone, so don't expect massive leaps and bounds in R&D year after year. At the end of the day, it's a grinding stone passing over some steel. No need to overthink it.
I like that Beam is backwards compatible. Hopefully in the future, they'll integrate it directly into the machine. IE, laser automates edge checking and adjustments. That's what I first thought when I read the release. Definitely would've purchased one had that been the case. Though, I don't know how useful it would be in a home setting. I don't check my edges often, because everytime I do, it just confirms that the machine is in fact accurate.
App functionality makes perfect sense. No need for Sparx to write entirely custom software. They're not making the mistake that automakers did betting against Carplay. In the future, expect the machine to have no buttons and be driven entirely by a smartphone. Additionally, it allows them to begin to collect usage and performance metrics, which can then be parlayed into further improvemnts in successive generations.
This might not appeal to users at first glance, but I think will ultimately bear fruit in years to come.
