I had a chance to try on the Twitch at an O-Store last week.  Wasn't super impressed by the style.  Very flat and square ... sort of reminded me of Men In Black, had they gone with Oakley instead of R@@B@@@. 
 
Price point is good, though.  I think it will really come down to colorways.  Some flashy colors may make a purchase worthwhile.  Which is something I think a lot of us think right now, what with all this hoping for the white/green colorway (which would look sweet with Emerald Iridium IMO).
