The content is generally based around some best practices, technical demonstrations, information on new products/features, and ways to connect with Synology. So I guess it depends on what you're looking for.
There's also generally time on either end to connect with the Syno team as well as MSPs/Integrators during and after lunch which is great for sharing ideas and learning about the ways in which others manage/implement Synology.
Historically these workshops will also come to EU. At least that happend the past three/four years.
It is an absolute go for getting to know the Syno people and other Syno based business.
On the content, they can not cover 100% and have to make choices. One year it fits and the next some less. That is ok.
Much as I'd like to move from the 2-bay DS218+ to the similar 4-bay (or better) and so bring the eSata Video Station library internal ... I'm happy to defer the purchase request with the CFO-who-must-be-obeyed.
They currently have a Chat integration with JumpChat /jumpchat
Syno is pretty big on free platforms/integrations where possible. Chat/Drive/Office are generally cost-effective alternatives to paid business/enterprise collaboration/communcation services.
