... but because PG worry about old users with old computers it generates into RAM. Maybe they have been losing old Win users and more younger Mac users are coming with faster hardware?
I really wonder how many people actually have old versions of BiaB on old computers; How good PGM's knowledge is of the demographics of users and their PCs.
I think I originally bought BiaB in 2013(?) but concluded then that the interface was not really compatible with the notepad PC on which I was trying to run it (~11" diagonal wide-screen). I abandoned BiaB and didn't try again until 2020(?). That suggests that for 7 years I was an 'old user who hadn't updated'. Various friends similarly.
What definitely is important/useful is that .SGU files that were copied to me by band members are still usable quite a few years later ... but most of the time I open the old file, adjust it to what I'd like with the current version of BiaB and save a copy in my personal songs folders. I think similar is also important for people like Bob Norton, who produce after-market add-ons.
But I can't help feeling that people on very old hardware are probably few and far between and if they haven't updated recently, quite probably never will.
I also can't help feeling that the combination of historic compatibility and a business model that seems to be driven by incremental upgrades has become rather a "tail wagging the dog" situation.
