Opening up a market is a contribution (singular) to the community, but this is a thin line to call "tremendous contributor". Wallmart was one of the major players in pushing USB drives and 3g modems to the public. Does this mean that Wallmart is a tremendous contributor to USB?
In what way has multi-touch been pushed way past what anyone has done in the past? (say, compared to Sears et al work from 1990?) Actually, any of the technologies on that list, in what way were they pushed way past what anyone else was doing in the past? Cornering the music industry (legally) was an achievement indeed, but a tremendous contribution? My thought goes back to Wallmart and any product that they was first to successfully sell.
