Wow... what a thread. I think we have a new champion here.
Productivity?
Suppose you can work 5% faster each day. Just suppose. How many days would it take to go break-even with the upgrade fee? Even if it's $1000?
Interface
Interface manipulation is also part of productivity. Not having palletes over the viewport is very common in Windows software, less common in Mac-software. But it improves workflow too.
Hardware requirements
I have been running the beta-version on my Dual P3 1GHz (from the end of the year 2000). It worked fine. All felt smooth. Lightworks rendering was faster then ArchiCAD rendering with better anti-aliasing, raytracing etc...
I'm not doing the largest buildings, but I guess there are a lot of ArchiCAD users that just make nice, simple homes. They don't need a new computer.
Add-ons
The developers kit is free. They also moved from Visual C++ 6.0 to 2003 with this version (on Windows at least). This means you need newly compiled add-ons to get it working in AC9. This is too bad for older and still usable plugins, but that's life in the computer business.
AutoCAD 2004/2005 support
The new DWG format is the single most reason why most AutoCAD users upgrade. To support it is very, very important for ArchiCAD. But not every user will need this.
LightWorks rendering engine
What can I say? I've suggested it a few times in the past, so of course I'm happy. It's integrated. It's fast. It's not perfect and it has some complexities in setting it up. I never got real soft-shadows from the sun, but I've done a few nice interior images that I never got out of the "photorealistic renderer" that has been in ArchiCAD since version 5 or 6...
There is no radiosity and no RPC-support, so there are people who will complain, but it works and does more then it's job.
And I still use 3ds max or Cinema4D when I need better renderings. I've finally started with Art*lantis, with the free version 4.0 from 3D-World magazine, but I'm still not impressed by it.
Stairmaker
Well, yes, it is what it has always been.
Stability
I've never lost any work. I hardly ever crashed. I did found a few interface-bugs and a few data-conversion problems, but no real killer crashes. Like was allready said: they didn't wanted to release another 8.0.
Although I loved 8.0 a lot: this was a true milestone, which features are much thorough and have a big influence on this version.
Would I upgrade?
As some of you might know, I'm not into commercial work anymore, so I can't spend money on ArchiCAD anymore, but I recommend the upgrade for it's productivity alone. And receive Lightworks as the icing on the cake.
