The first moment I saw it, I stared in awe. I knew exactly what I wanted to do with it: DJ tablet. This is the video that inspired that idea: http://www.youtube.com/watch?v=vaiRLpuwDZ0 The XPS 18 tablet is just the right side for finger input on Traktor @1080p, it has a battery that can last through a set if power isn't available, it is configurable to a i7 core and 8GB RAM. With a lot of companies cutting out there 17" line of laptop (except in gaming machine), this thing will stand out in a crowd.

What other uses do you think the XPS 18 could have (minus the Family AIO/tablet or Kiosk)?
