But people naturally compare them anyway.
You have to admit there are lots of tasks that don't require realtime control where people could choose either system.
I think the Arduino shield system is brilliant, and the equivalent on the Raspberry Pi is not as well thought out. This is the biggest shame of all.
My top few wishes for the Pi would be:
- a well-thought-out, open shield system
- 4 support holes at the corners instead of 2 in the middle
- maybe a better case design - all ports along one side maybe?
- an SD card that would insert fully
The Raspberry Pi is wonderfully standardized, but the Arduino seems to evolve in a darwinian fashion because many vendors can make them.
The Arduino comes up a little short in tcp/ip connectivity, where the raspberry pi is brilliant from the start.
