Raspberry Pi is the most economical solution to do computing of any sort. You can choose this solution for any of your problem and it might save you a lot of trouble where other traditional computer might demand something more from you.
Recently, price of Raspberry Pi 4 with 2 GB ram was reduced in price and its new variant is released which is just $75.
There is not much of hardware change in this new release other than memory increase. This means that 64-bit version of Raspbian OS can now more efficiently manage and use memory and provide more robust solution.
These open-source solution can be the future of computing and as we already know that open-source OS Linux was considered for satellites communication. This could put emphasis on more transparent open-source development and break monopoly of few tech organisations.
