Yep. :-D
I have no regrets about upgrading to OS3.9. It's well worth the £20 I spent on upgrading, thanks to things like Amidock and the ability to address more than 4.3Gb capacity drives. It seems to be a stable platform too, as I haven't had any stability problems despite adding hacks like Magic WB, ReqAttack, VisualPrefs etc.
The only issue I had was with one of the Boing Bag updates which didn't like the RemApollo utility I was using for my Apollo accelerator card. However, the offending script can be commented out of you startup sequence.
