Strange, I had a problem with buffering on WiFi and the router was next to the TV, by using the Ethernet cable the buffering problem disappeared. 100mb is more than enough for at three simultaneous 4k streams which should be more than enough for anybody.

We use the serial port to connect to a liquid scintillating counter that was made before USB came along.

The Counter still works so we have no need to replace it.

We have however had to replace the Computer it is connected to because various parts of it, suck as the floppy disc drive failed and we needed to sort out some additional data storage.

We originally used a 4k PET machine with 2 5.25inch floppy discs.

We had to rewrite the software on a 286 based PC with DOS and a 40mb hard disk in the mid 1990s.

Various companies have tried to persuade us to upgrade to a more modern LSC but they are too expensive for the amount of use we get.

None of the these use cases is what the Raspberry Pi was designed for, a cheap multipurpose device for learning and design.

The main PC is designed to be a full PC, but in a smaller box.

The main advantage of the Pi is it's initial low cost,and simplicity. It is virtually impossible to completely brick a Pi and considerably cheaper to revive a software bricking.

So what you are saying is that an SBC that costs around £80 cant replace your £1000+ Apple kit because it doesn't play well with other Apple technology.

We get it, your an Apple developer/user.

For people who aren't wedded to Apple it can do all of those things you say it can't, it just doesn't work as well as the Apple stuff costing 5x the money
