I'm the guy behind this - I just woke up so I'm a bit late to the party :) It's really good to see a decent discussion here... For me, it's about getting the right tool for the job. I'm mainly a C programmer, but if I want to manipulate a bunch of files I probably won't use C, I'll use Bash. In the same way there are (a lot of) times when what you actually want to do with hardware is quite simple, but you'd end up writing a whole bunch of C code to accomplish it - and that's where Espruino will not only be faster, but a lot more fun :) Someone also mentioned power consumption/events and I thought I'd give you some figures. When Espruino sleeps between events (which is does automatically) it draws ~50uA. Even with explicit power management calls, pretty much all Arduino boards draw at least 5mA (so 100 times more), and without explicit calls it'll be 20-30mA. Raspberry Pi is anywhere from 100-500mA, so over 2000 times more power.
