there's nothing better than a used PSX for homebrew at a home console. Pretty damn cheap too, and fairly easy to code for in the retrospect.
If i had a couple of hundred billion and owned an electronics company i would definatly start building a console for the next set of xbox, ps4 and nintendo even if i knew i might not succeed and loose alot of money. Sadly i don't have billions and don't own any companys.
