It’s expensive and impractical, but in a way that also helps to keep it aspirational–still very common in the electronic music scene, go to any of the festivals or clubs in Europe and they’ll have the technics next to the CDJ’s.

Controller - laptop setups are common for house parties, and for bars and events that keep the same dj all night, but less common in clubs where the CDj’s with USB sticks make it easy to switch over. A CDj needs a DJ mixer, to which you can also hook up a record player, so mixing both is not too hard.

Personally I find vinyl a bit daft for new music since it’s all made on computers anyway! For older music it makes a lot of sense though, much of it never made it to digital.
