Yeah I've got to get a LapLink cable for my laptops. Will definitely come in handy.
As for the whole "purely vintage" stuff, in an ideal world I'd have a big network of vintage PC systems that can all network together and stay "pure" with no modern hardware involved. But the issue is that I don't, and getting that set up is really expensive. As for spinning rust, I certainly do love it. Most of my PowerBooks are running their original SCSI drives and it certainly adds to the experience, but thing is, they die! 30 year old drives are dropping like flies and if your 20MB IDE drive kicks it like mine did, a replacement that will probably also die in a couple years will cost you $100. Versus $50 or more for a modern solution that will keep the vintage hardware running for the next 3 decades. We can all wish that someone would manufacture new noisy low capacity hard drives for these computers, but that's unlikely to happen. If I do run into a working drive I usually leave it if it's in a 90s system, unless I need the extra storage of an SSD.
Starting around the XP era I want to get everything SSD swapped because those drives are quiet anyway, and there's a big speed gain to be had. Eventually all of my systems are going to need them to stay running, old drives die.
