Short-finned pilot

Bringing Android, a smartphone operating system, on board alongside Windows Seven is a real gamble.

Android is biblically simple. It starts up first, and very quickly. Then you move on to Seven, which looks a lot like Vista and will only shake up a few habits. Android, on the other hand, satisfies only the most basic needs. And its many free applications are rarely adapted to the device, so are sometimes not recognised. All in all, the D250 is still a 10-inch: its screen is small and, above all, its keyboard is impractical.
