The author is probably presuming computer equipment, but I'm mostly a musician that dabbles heavily in computer tech enough that I am a bit of a computer geek. In my studio, I still a lot of vintage gear for my sound. I love my vintage Marshall amps and my Laney. My main guitars are a 1957 Les Paul, a 1959 Les Paul, then I have a bunch of '80s era Kramers and Charvel superstrats. I use MXR script pedals often as well as vintage overdrives. These days, a lot of musicians have moved on to all digital effects with a lot of amp modelling, and they're getting pretty good sound. I am gradually moving to computer based production. For a lot of musicians, a Mac laptop or tower running Pro Tools sits alongside amps, pedals, and guitars that are 30+ years old, and you get this anachronistic combination of ancient microphones and new DAWs. Visually, it's enjoyable. I also like vintage synthesizers, particularly the Roland, Korgs, and the Yamaha DX7 keyboard. Today, many keyboardists use computer based synths and samplers to mimic the sounds of these old keyboards. On my iPad alone, I've got a virtual keyboard app that does FM synthesis and may possibly read in the patches from the DX7. I'm also using a virtual app that emulates the old Fairlight CMI. I still have no idea what to do with it.
I still love analog recordings. I in fact prefer them to digital, so I've got a turntable setup that feeds into my desktop, making my music collection a combination of miniDisc, cassettes recorded on a Nak, FLAC and AC3 made from vinyl sources that were run through a tube preamp, and then the regular assortment of MP3/AC3 and FLAC you collect from across the Internet. I'm also a photographer, so I've got a collection of very old manual focus K-mount and F-mount lenses that I use on dSLRs today.
I also still have old game consoles plus DOS era video game diskettes, but most of the software has been virtualized by now, so maybe that doesn't count for much.
I can't say I'm one of those practical types that enjoys reusing old things for the sake of it. I have very few of the many computers I've owned for example. I'm just very much stuck on what I like.
