I have a question for you, how much memory is 2 qubits in terms of bytes?

As long it runs Windows x64, no problem

Very cheap
We can start to worry about internet security

Never ever.
But Qinux should be fine too

It has nothing to do with memory.
It's more comparable with 32 or 64bit of CPU's.

But the main point is that one qbit can not only represent 1 or 0,
it can be all from 0 to 1 so it is an analog bit

The current record is hold by IBM:

rather, yes no maybe

How do they cool these down to the temperatures required for their operation? I thought 99% of the reason it's infeasible for anyone to have a quantum computer is due to the cooling requirements and that whole vacuum thing.

There are different methods of getting qbits.
At the moment you can get also up to 6 qbits in silicon:

For such type of qbits you don't need extrem cooling down to near zero K.
