Oh awesome more more more more more.
I think DaVinci may actually be pretty straightforward. It's less like SMC than Savoir Faire with a splash of Technical Writer. SMC does all the coding itself. With DaVinci you have to know the code, DV just compiles and installs it for you. (Here I may be cribbing a bit from Why I Run.)
edit: Plus, of course, it also works on hardware, gene treatments, nightclubs, and people. Um. I guess the main thing I was going for before neglecting that crucial detail is that it's a predictive helper algorithm like Savoir Faire, and it just generally becomes smarter and better connected as it spends more time snooping around corporate servers. You don't need to handwave away any retroactivity; either it knows what you need better than you do, or it's just getting increasingly good at procuring anything.
I'm not even gonna try with Bookmark, except for the art, which I interpreted as some kind of Augmented Reality deal. Like, that big glowy in-your-face thing isn't the hardware itself, but rather your virt's "Mount External Storage" icon.
