Thanks for everyone's response here. I've been reading it every day, but, mostly I've been laptop shopping and "reading, reading, reading" reviews, specs, etc. and trying to learn my PA3x in between.
I'm in "laptop overload" at this point. Gary said pretty much just buy anything and make it work. I'm on the verge of doing that, but then I think about using the notebook for DJ jobs, and singing Karaoke on the nursing home gigs like everyone on the planet is doing now. I have about 2,000 Karaoke songs so that's a real good thought.
I'm still looking, and your advice here is extremely helpful as musicians, I believe, have special audio needs.
