but once you get to most of the ARM processors it is harder to make them

There are many ARM SOC chips that are half way between an Arduino and a
Raspberry Pi. They have GPIO and various serial ports and counter/timers.
They don't have USB, Ethernet, or a display controller. They do have on-chip
RAM and Flash.
The teensy from PJRC is a good example - uses the Arduino dev
environment and has all the easy to use libraries, but is a LOT faster
and has better peripherals. Or you can use other dev environments. It's
an ARM Cortex something or other.

The BeagleBoard Black is a bigger, more capable example.. You can
actually run a *nix on it, but has device drivers and such for lots of
GPIO and timers.
