Every time I read an article like this it hammers home my only true beef with the Wii... that the lack of SD support, and in the larger sense, Virtual Console and WiiWare implementation sucks so badly.
To this day, downloadable games are my favorite part of the Wii. Sure, I'm enjoying their main releases, but my gaming tastes have changed as my free time has shrunk and nostalgic and/or short gaming bursts are what make me the happiest at this point.
I think this really begs the question, were these design choices made intentionally, or is this evidence of a lack of experience at the system level by Nintendo's internal developers?
