Sony state this is the world’s slimmest full HD smartphone, the world’s largest full HD smartphone display, the world’s sharpest large-screen smartphone display, and the world’s fastest smartphone processor.

Even more bizarre is the Xperia Z Ultra can be used with any pencil and selected stylus or pen (capacitive stylus or metal pen with tip diameter over 1mm). That’s right. You can use a pencil on the screen.

My initial thoughts are huge device, top specs, waterproof, and no need for a special pen like the Samsung Galaxy Note range. I do wonder though if 3,000 mah battery is big enough to power this device for a whole day.

So would you buy this as your only device?
