I am also not so young anymore (63) and using SAM8.03 since 5 years and find it the best ever daw software.
I've started with Cubase(SX-5.2-Nuendo) went to Protools le (could not afford the real thing), than found sam7.xx and was sold forever. I had it down in a couple of days before i could front clients, record and mix flawless or at least to them it loked like i knew evrithing 'bout the software. soon i stoped using other tools (like ACID to make samples etc) I do everithing in sam and if i had the juce I'd go and update to the latest version, I'm realy impresse the way it looks.
I also use fw1082 now that I'm working from home(a smaler studio) I've made a list of how and what you need to have a good functioning PC-DAW using ASUS and dual core. Asus_Firewire_DAW.doc
