Yeah, it seems strange gaming isn't listed as a targeted use. IMO that would be the ONLY use I could think of where it would be useful. As others have stated, its vertical resolution is just way too low to be a practical work monitor considering its price; $8000 (or even its cheaper predicted price of $6500) would buy several 30" screens.
Really, the only areas this thing shines in is its response time, and its curvature should help its utlra wide form factor to be more immersive - both attributes absolutely shout gaming goodness. Of course there's the pitfall of getting games to support such a wide resolution, but the ones that could would undoubtedly look amazing.
