Yes, but in embedded there are huge differences between the various
boards and processors. While an rpi is a great device if you want
to do graphics based stuff, it's a very poor choice for control
and measurment applications, or anything that needs fast I/O

Actually, of the 15 Raspberry Pi cards I have only one is used in a graphics 

On the positive side they work very well with external devices for control 
and measurement, and have a huge amount of software and hardware support for 
a vast range of devices which makes for fast and easy development.  On the 
negative side, certainly they are not the fastest of devices, although the 
current quad-core RPi3 is capable of handling thousands of messages per 
second, and having Ethernet over USB won't give the lowest jitter if 
sub-millisecond timing is important.

I will be interested to see what is recommended for a 100 kHz event rate.
