Very different supply lines. Bevereages companies have many bottling facilities distributed throughout their markets, electronics companies tend to have relatively centralized manufacturing.
With low value:weight beverages, transport costs dominate manufacturing, so it is most economical to have many bottling facilities relatively close to consumers, at the cost of reduced manufacturing economy of scale. With electronics, manufacturing costs dominate transport costs, so it is most economical to centralize manufacturing, taking advantage of economy of scale.
Of course, sony could work with some drinks manufacturer to hybridize those supply chains, but I don't think there's value in doing this large scale. This is a (great!) marketing gimmick, and they can get most of the value by doing it one-off. There's not a lot of marginal value in scaling it out.
Bottled water, though, is often absurdly centralized. Dasani bottles might get filled at a relatively nearby Coca-Cola bottling plant, but Fiji's water really does come from Fiji. Despite the outsize logistics costs associated with doing so, the company still manages to make money selling it for only a couple bucks a bottle.
