IMO devices based on an ARM core with built-in flash and RAM are all in the same 
category. The size of the package as such - within reason does not exclude a device
from this group. Even a 112 pin TQSOP is still quite small for essentially a complete
32-bit computer.

Regarding te matter whether these other ARMs should be discussed here. IMO 
announcing alternatives here is good. Discussing differences in implimentations is 
good. Especially pointing out gotchas that might be present in either the LPC2xxx 
device or the alternative (i.e. not present in the LPC2xxx). Discussing non LPC2xxx
devices outside this context should be done in an alternative list/group.
