Difficult to judge because:
- not a lot of screens to judge on (where are menus,...)
- it is only 80% finished
- there are 4 screens and they are all different, so which is the one i will get when i install OS4?
Good things:
- the fonts
Negative points:
- still looks old and dated (looks like a 3.9)
- i don't see any work of a graphics artist here, none. The textured window border and the grey pattern look ugly (mysterious graphic artist: i hope you will not include this in the final look)
- it looks cluttered, depressive, dull
- the glowicons don't really cut it anymore (i had hoped that Mason would do some magic with icons somewhere in OS4)
For me, really dissapointing. I hope a lot changes in the last 20%. (btw see Simoami's stuff on what can be done to make a modern look)
