I'm definitely qualified to answer

I bought a C2 and I will buy the Hub as soon as I can. I will add:

C2 has a 30 day warranty and requires some (simple) assembly
Hub has 2yr warranty, ready to use it the box

The reason I'm switching from C2 is its lack of multichannel PCM (FLAC) support - wrxtasy said this may be fixed soon! (although I really only bought the C2 after waiting ages for the Hub's release, at $100 I thought I'd 'have a play'... )

I've been using Kodi for a couple of years and ideally if you have a fairly large movie and music collection with plenty of meta data, 8GB eMMC is probably not enough. Wrxtasy (I think) said its not user upgradable on the Hub. Having said that, maybe I can configure some of the metadata to be saved/read from my NAS - I've not looked at that yet.
