A lot of people have already mentioned that they are too large and expensive for consumer devices. They also need to be cooled to temperatures very close to absolute zero (using liquid helium) for the superconductors, which adds additional bulk and power draw.
These quantum computers would also require a different architecture that isn’t supported by the majority of software and OSs, since they work very differently to standard non-quantum chips. Think how RISC-V isn’t very well supported too well right now, and it’s much worse than that since the logic gates needed for computation, storage, etc. need to be rewritten entirely due to the use of qubits over bits! Aside for some very specific research bits, there is nearly nothing that can currently run on a quantum computer.
As of right now, even the largest quantum computers only has a few hundreds, maybe a few thousand, qubits, which isn’t enough processing power for running a regular desktop OS and consumer applications, even if everything was magically ported to quantum land. Not only that, major hurdle right now is reducing environmental interference from affecting the qubits, meaning there are currently high error rates, i.e. the qubits do not behave.
