I forgot to mention that the default look is not 100% finished yet, they are still working on some minor details.
Note that these screenshots show antialiased fonts (sadly, the rescaled and jpeg'ed screenshots make this look rather "blurry") and Gradients - two features that were not publically mentioned yet.
Have they fixed the AmigaOne G4 bugs yet?
There are no "G4 bugs". A certain competitor claims that there are such bugs, but he refuses to come up with any evidence. The G4 performs exactly as we expect it to perform - EOT.
There is a DMA bug, caused by a well known bug in the southbridge (VIA686B) which is not 100% fixed in the current Linux kernel - the next kernel build should fix this.
