given that beta-testers are, and have been using, the system for a while, you're better off asking them.
They cannot answer. They're under NDA.
So I assume, given your intense interest, that you're looking to buy one?
Most certainly I am not. I have better uses for 2.5 k€.
I'm fairly sure that the 4.2 release isn't "mysterious".
The actual content of the 4.2 release remains a mystery, as well as the possible release schedule. It could be several years, and whether things like 2nd core or full 64-bit support will ever be achieved remain a mystery. All quite relevant questions considering the nature of the HW being sold. Running 32bit single core OS on such HW is much like (..reader beware: car analogy follows) buying a sportscar and disabling 3/4 of the engine.
Piru, I appreciate your coding skills, but please consider how you come across with these type of posts.
I guess I've never cared about appearances, and I'm not starting now.
