As a software engineer, I spend $3k or so every few years on a MacBook Pro or similar. I see no problem with spending $3-$5k on an iconic drum machine that will continue to last for decades with basic service if you think you need it.
There are other threads that debate musicianship, but the reality is that once you have basic skills, music is a meme game like any other form of art. You need the symbols of office for clients to take you seriously, and for some musicians that’s an OG 808, 909 or 303. Or maybe a 1200 and an MPC of some kind.
Or maybe you always wanted an 808, finally made some cash, and decided to buy one. Still less than the depreciation of a new BMW-Mini (which is a 1/2 series under the Mini drag) in the first year or two.
They might even be useful tools.
I’m happy with my TR-8s - it gives me easy access to the vintage Roland sounds with a reasonable amount of tweakability. The MD is good for more intense sound design. I’m more likely to get a Rytm, Syntakt and Pērkons before I spring for vintage Roland hardware, but that’s just because I don’t feel the need.
