My children's initial experience was it doesn't work properly.
* It doesn't boot up ready to program. It boots to a linux configuration box.
* There is no help or how to get started outside of the usual linux stuff.
* It doesn't work with all HDMI devices, It's the ONLY electronics product I have ever come across that requires me to edit the overscan settings
* It doesn't work with MANY popular USB devices even some Hubs fail to work with it
* If you don't get the right power supply you will encounter weird errors.
I support RPi, I'll buy the next generation but this version is NOT ready for those hungry kids out there.
When we got our first Micros they worked out of the box, came with extensive manuals and getting started guides and were great fun. The RPi seems like a chore to get started with. Once setup my kids were off but of they were on their own they would have been stuck.
