Yes, it's pricey, especially considering the extra components not included in the box that have to be purchased separately. If price is not a critical factor though, it undoubtedly has advantages for projects where a high degree of custom setups, compact form factor or peripheral attachments are required.
Maybe good for development while trying to figure out what gizmo and horse power you need.
If you are using Deep Learning I am not sure the GPU gives you any real advantage because it doesn't hardware
accelerate Googles Tensor Flow. I find it odd that AMD isn't doing that? It seems that is staying away from AI
by not offering GPU acceleration for Tensorflow.
The Intel Movidius has still to come up with a solid offering that you can just plug into Tensor Flow .
