That maybe doesn’t apply to 80-90+% of the userbase, though. Vast majority of users for any DAW are hobbyists who’s other ‘serious’ work enables them to invest into software like Cubase. And very many have both a desktop and laptop for music for the software to run on.
I have a studio where i work from during the day which has everything connected, and i also like to compose/mix at night from a laptop inside my house. This means that i have to go to the studio, pick the dongle up, before i can even load Cubase at night. OR, i have to transport the dongle with me 24/7 just incase i need to use the software at any given time on either machines.
So whether you’re “seriously” working with it or not, the dongle is certainly a big consideration when looking to buy. And that’s why Steinberg have hinted at moving away from it in future.
