I did out of curiosity however I got stuck after having seen the splash screen, I was not allowed a glimpse of 2008 on my test laptop, because when the X-server starts the screen turns black and evrything keeps silent.
We'll have to wait a bit more and be patient... update
On my desktop PC I came a bit further, into graphical mode in enw COMAR installation version. There is an annoying bug here in that the cursor/mouse pointer can only be moved vertically up and down the sceren in the center, horizontal movements are not possible.
Using TAB and spacebar I worked my way through untill the partitioning part where also are some minor translation issues left.
I did not want to take the risk to go further than that point.
We still talk about a development ISO however, which means that by mentioning these problems I encountered I do not want to blame anyone at all.
Work is still in progress and obviously 2008 is almost ready for launch....
