"... completely locked-down"??? A bit too far, G... Tell that to the folks at BMUG and the thousands they inspired to open and extend their Macs. And what about BMUG's notable offshoot, Farallon, which began as a handful of BMUGgers' hacks (PhoneNET, MacRecorder, and Soundedit). Or those who used ThunderScan which converted an ImageWriter into an image scanner.
Yes, one needed a Torx screwdriver and two hands to open a Mac case, but it was far from "impossible to open." And it was trivial to get (or make) an adapter to use a "standard" DB-n plug. And yes, there were no slots (until later), but on balance, nearly every design decision Jobs made was sound.
I'm no Jobsophile, but I never had a problem with the Mac being so closed. To this day I need zero anti-virus or spyware software.
I, too, miss Woz, his contributions and philosophy, but Jobs's Apple needn't apologize.
