Your argument is rather muddled there to say the least. You start off talking about consumer hardware then bring up an anecdote about a developer writing userland software against a developer board (ie non-consumer hardware) and use that as an argument that the Linux kernel is hard to develop against despite there being nothing in your anecdote discussing kernel development. "Anacdata" is always going to be pretty sketchy in any technical debate but here it seems especially so since this isn't even your own first hand experiences (let alone relevant to the point you were trying to prove).
