You'd make a good Google (Bloogle? sounds like an alcoholic drink to me). I really like this approach. Especially if anyone with Google and a toolbox can fix their phone. It's weird, now that you've put it like this, that they want to go completely modular and not just in a more modular direction. Currently you need an expert to pull apart something as sophisticated as the latest iPhone. So in response these guys want to go overboard and use something like Lego. People just want to be able to pull apart their devices (and replace them), is that too much to ask? You'd still have the same benefits but less of the my-phone-mighy-fall-apart-when-I-drop-it stuff.I'm not Google though.
Then I'd come out with a chassis that doesn't go together like legos, but can be upgraded in fifteen minutes by a semi-skilled technician with a satchel full of tools.
