I had licencing issues when we first bought it (it was on sale for $600!), and it took at least a month or so to figure out what the issue was. Element14/Newark support was not helpful at all, but the guys at Altium were quick to resolve the issue. I don't really understand why they have to partner with Element14/Newark, they're completely useless!
As for the software itself, for non power users, I found it was actually pretty good compared to my previous work in Altium Designer. Sure, there are some things that are missing, but I was able to easily import my library files, rules, etc. and most of the functionality for simple boards was there. I'm still able to import a DXF for a board shape, and export a .STEP 3D file to check fits into my parts, which is crucial when doing mechanical and electronics assemblies.
For $600 I'm actually pretty happy with it. If you're a power user though I can understand that missing features would kill productivity compared to Altium Designer, but for me, the functionality is similar enough that I can recommend it.
