Well.. it's still at works, and IMHO not fully suitable to be given to 'non adwanced users'. But OS comes in price of system and updates are free, so it's a good start. :-P
One thing you and others here might not know is that latest MOS version is from sunday (9th Feb 2003). And based what I have heard from Non-developer MOS users, it's a lot better on that usability/stability compared to that older Pre-Xmas release.
There are actually many 3D drivers in package, but all are for those older cards (like woodoos), Radeon 3D drivers are not yet there. Otoh, Q2 works faster on Pegasos using software render than on old wos-PPC Amigas with HW support. :-D
I have heard same about networking... A bit sad but considering how long MIami has been abandonware it's a bit difficult to make them work together 100%.
IMHO Amiga Workbench was never any 'high usability tool'... Well, ofcourse if one add tens of hack to it it'll become much more usable, but compared to Plain WB I don't think Ambien has much to lose. And One thing Ambient definitely has better, it looks can be configured widely in system-friendly way.
