Erm....didn't they say exec was complete a couple of months ago?
They did but IIRC they were adding in extra support for Virtual memory, etc.
Its nice to see all the positive reponses that have been posted on this site regarding this announcement.
On ANN everybody was moaning for one reason or another (what does done mean!?!? is it finished or not, moan moan moan) :-x
I personally am encouranged by this (though it would have been nice to see "Its finished guys, go buy it"), Hopefully we should get to see the OS in action on AmigaOne at the WoA.SE in November (i dont expect it to be on sale by then, if we still have to go through a Beta test stage)
