IF they had the Uranus - and this would be the only machine I'd show interest in - I'd go there for picking one up. So for answering your question: No, I won't buy until they show a working Uranus.
Is Uranus non-working?

So far all to come out is specs and rendering. No working prototype or proof of it actually existing.
Sooo,it's too big to come out

It's not about it being too big. It's about it having a power efficiency no one else has announced on the big guys.
So a rendering is not really proof. There needs to be proper release to prove it's not vaporware.
