Instead of having 3 USB together why not have a concaved port for the USB system drive.
I would like to see cheap plastic electronics considered for 1-16 GB SD ROM standards for music, movies and games ect some of which could be sold for the raspberry pi.
I would like the processor and system to handle 60hz double 4K output.
I would like a more modern GPU.
I would like to see bigger RAM options like 8 and 16 GB variants.
I would like raspbian to start a 64bit variant.
I would like closer to a PS3 performance say 80-140 GFlops.
I would like 2 module options one with better GPU performance and one with better processor performance.
And 4 USB drive slots on storage modules.
All these modules can be put in a small rack neatly and act as servers or for deep calculations.
I would like to see more software exploit racks.
Raspberry Pi 5 should be a move more towards those who can't afford 200,000 pound systems but can build up small scale computing solutions to do more with electronics and computers.
