If you get into programming or other computery stuff the number of computers in your home inevitably starts increasing.
It was like this in your case too.
Programming is one of the cases where the more classic designs of a "personal computer", like a "laptop" for example, are still justified so you needed to acquire this kind of equipment too.
Acquiring new things usually involves buying them.
Buying things costs money.
And reducing the amount of money you have is generally not desirable.
With these conflicting requirements some optimisation was needed.
You quickly realised that it makes more sense to get a used computer than a completely new one.
The price of a used computer is often highly reduced compared to a new one.
But its actual value is generally not reduced as much as the price.
With some looking around you are able to find a computer which has all the required features and an acceptable price.
This way, one day not long ago, you bought a computer and got involved in all this stuff which is happening right now.
