Apple's latest iPad Pro with cellular

That, really, is the only question that matters with the new 12.9-inch iPad Pro. 

It has a new type of display so I think it's the best thing for watching movies that isn't a high-end television.

It starts at $1,099 for a 128GB version, but expanded storage and accessories like a keyboard or Apple Pencil can add up to the price fairly quickly.

You usually see two basic types, LCD and OLED. Both have pixels that combine red, green, and blue subpixels to create color. 

but you have to actually light up the display pixels to see those colors.

 OLED pixels are self-illuminating; LCD panels illuminate display pixels by placing one, more or more LED backlights behind them.

Mini LED, the technology powering the 12.9-inch iPad Pro display, is designed to bring the LCD panel as close as possible to OLED's contrast and black levels.

Its display pixels are not self-illuminated, but back-illuminated. The trick is that they are illuminated by 10,000 tiny LED lights.

It's almost like a backlight, a low-resolution screen behind the screen, tracking the image and making sure the black parts of the image don't burn out.
