In fact, lots of devices with that capability are coming to market: they are all those Allwinner-based netbooks and tablets that can also run some form of pure, multi-tasking Linux. They'll run web servers, interpreters and compilers. They'll run Java SE. They'll run the GAMBAS IDE.
Some Arm chipsets like the Allwinner can now be considered as the true spiritual successor to the PC. Although some aspects are closed source, workarounds will be found and even some closed source drivers can't hurt. It's just like the PC era when people were trying to reverse-engineer the PC BIOS.
