What whould your perfect device look like? If you can have anything you want (within a reason), is there a perfect form factor/specs/price combo?

Please divide your propositions into these few sections:

DESIGN

  • screen size
  • thickness
  • weight
  • form factor
  • input (touch, pen, etc...)
  • ports
  • casing/chassis material

SPECS

  • OS
  • screen resolution
  • CPU/GPU
  • RAM
  • storage
  • connectivity
  • battery life
  • camera
  • additional features / sensors

PRICE

  • please, be reasonable and realistic - it's quite easy to "design" device worth 2000-3000$

ACCESORIES

  • covers, docks, batteries, input devices, etc...



My perfect device?

DESIGN

  • 12.5 - 13.3'' screen
  • 15 mm
  • 1.2-1.3 kg
  • convertible (Yoga-type hinge)
  • touchscreen with active digitizer + pen inside (Wacom)
  • 2x USB 3.0, 1x display port, 1x micro HDMI, SD/microSD card, Jack 3.5 mm, magnetic power port
  • carbon fiber body

SPECS

  • Windows 8.1
  • 3,200 x 1,800 screen resolution
  • Fanless Broadwell (when it's ready) or Haswell with fan (for now)
  • 8 GB of RAM
  • 512 GB SSD
  • WiFi 802.11ac, Bluetooth 4.0
  • 9-10 hours of battery life (real, moderate usage)
  • front-facing 3-5 Mpx camera (1080p video)
  • gyroscope, accelerometer, ambient light sensor

PRICE

  • 1300$ (I think that's high but reasonable price and I can spend that much for a device which can replace my tablet, laptop and desktop)

ACCESORIES

  • dock with dedicated graphics, and HDD

No GPS, rear-facing camera, 4G/LTE (for keeping the price reasonable).
PS: It looks like I want succesor to Thinkpad X1 Carbon with yoga-like form factor, new CPU and pen support.
