I must admit I find the whining about the performance of the Pi on a forum where a large number of members still stick to hardware with CPUs where double digit MIPS values are considered fast...
It's not like people here don't know and understand that you can actually do a lot of fun stuff with *really* slow hardware.
Especially when the cost of the Pi is practically a rounding error compared to a what a lot of people here regularly spend on hardware...
Someone who complains about the speed of the Pi just instantly demonstrate that they don't get the point of it.
