Apple Logic Pro /LogicExpress Discussion

OK, I've been using this thing long enough to make a couple observations about stability 
now.  I upgraded from Pro 6 on a Dual G4 with ProTools Mix Hardware, system 
9.whateveritwas.  This system was medium stable, with occasional "freeze" crashes or TDM 
errors.  Problem was, any crash was a disaster because it took about 20 minutes to re-
boot the program (very large exs library).
So now I've bagged the ProTools hardware, and I'm running Pro7 on a dual 2.5G5 with an 
RME fireface.  I had some initial problems with "kernel panic" crashes, which turned out to 
be because of A) the fireface needed a firmware update, and B) I had a DV video deck 
sharing a firewire port with the Fireface.  Bad.  Since I sorted those things out, though, my 
initial experience is that Pro7 was COMPLETELY stable.  Not one crash.  At this point, 
though, I was not using ANY 3rd party plug-ins or instruments.
Note the word "was."  I installed the Spectrasonics suite of instruments (Atmosphere, 
Trilogy and Stylus/RMX) and they were cleared by the logic authorizer.
I started working on a piece with about 12 instruments, including 4 instances of the 
Spectrasonics stuff.  The System activity monitor indicated that the computer wasn't 
working very hard, but the song repeatedly generated crashes of the "unexpectedly quit" 
variety.  The easy work-around was to Freeze the Spectrasonics tracks (love that feature) 
after which the song was 100% stable.  
But I would say that Logic is still quite unstable when dealing with 3rd party stuff, even 
when cleared by the AU authorizer.  But with the Freeze feature and the blindingly fast 
reboot time after a crash, I have no regrets about the upgrade.  I'm looking forward to a 
bug-fix release.  I hope Apple focuses on increased stability as the first priority- that's the 
only "feature" I care about seeing added at this point.  But with the all the new features in 
7, plus all the features from 6 that I never had access to before because I was working in a 
TDM/DAE environment, I have to say I'm completely blown away by the current version.
