Honestly I never understood this.
You can buy a more powerful desktop computer.
There is no reason to have a portable computer.
I don't give a shit what your deal is.
If you are homeless then you should probably sell your computer for food or rent money and work on getting job.
This is why America has public libraries.
I used a public library to get a job when I was living out of my car.
So yeah. Those things are pointless.
