I think the Vera units are important for the DIY type folks. Reasoning is the connectivity to legacy Ademco/Honeywell and DSC type alarms with the AD2USB adapter. Home automation requires programming/customizing, and its almost always unique so you need someone who can cater it to the individual users tastes and preferences which means you need something very feature rich. Vera works with Nest thermostats, DIY sprinkler systems, i mean you can somewhat pick and choose which solution works best assuming you already started building out your home automation setup. I think many folks who want to do home automation want to integrate their existing infrastructure, so the Vera offers the most compatibility. Honeywell sensors and equipment are fairly cheap since ADT predominantly used their equipment for their residential and commercial installs, so they are affordable to upgrade and expand vs buying a bunch of wireless sensors that may be pre-packaged for a newer z-wave setup. The z-wave will be easier to setup though and for some people learning how to address the ad2usb adapter etc will require more expertise. The Vera stuff will have its place in the market until there is a more standardized group of sensors and connectivity methods multiple industries can agree on integrating into their devices/equipment. A lot of stuff is going toward the apple-esq look, but it looks terrible and functions to such a simple level its not very effective when it comes to tailoring to users needs/lifestyle.
There isn't one system where I liked all the design elements, so i hodge podged the automation of different equipment in my own setup. Luckily the Vera unit was able to tie it all together and that is where it was gold for me. Don't get me wrong the Vera units have their shortcomings, but like most of home automation it is routinely improving. I mean apple and google still have nothing outside of buying up the people who are trying to improve this sector.
Honeywell is missing the boat and playing catch up in an industry they should have driven further. It's growing but there are options.
