The thing is slow because the ARM core is tagged onto the side of the GPU. The chipset is designed for throwaway STB uses. The ARM core isny much faster than a 100MHz SPARC 20 I have. About 15% faster. The IO also sucks. For a general purpose computer it's painful. I posted instructions on how to make it fail on the RPi forum. My thread was deleted. The boot and video detection process is a total mess as well. Daring to suggest that is the case is frowned upon apparently as well as I was basically flamed for wanting to use composite video over HDMI. Bear in mind I didn't have an HDMI capable unit around and the thing is marketed as composite capable. Also I was getting USB brownouts with a powered hub connected. My thread was deleted. I've worked with embedded systems for a number of years and the RPi was a really low point in head bashing on wall. It's an awful platform. Its in the bin where it belongs.

I am not sure what 'throwaway STB' means - something to do with phones? How many watts does your SPARC consume? I think the rpi makes a better stab at being a general purpose computer than an android tablet, and I think that the wayland port should improve it further. However I agree it's no replacement for a power hungry intel box. Post the instructions here, I will test on mine to see whether it's a general problem or just your box - there have been faulty ones shipped, but it's a tiny percentage of the total. Having threads deleted seems to be a common theme on popular forums, it doesn't usually signal a cover up - the moderators can take exception to your tone and then you have no recourse. When my rpi posts it seems to look for a hdmi cable, if none is present it outputs to the yellow composite - how does yours differ? I can't understand if you mean brownouts in terms of power or in terms of connectivity - what was dropping out? I can't say I have any experience with embedded systems but typically when people say that they aren't referring to computers that the rpi is comparable to - e.g. hdmi out, usb, ethernet. What were you doing with the embedded systems that you couldn't do with a pi?
