Returns true if this is a low-RAM device. Exactly whether a device is low-RAM
is ultimately up to the device configuration, but currently it generally means
something in the class of a 512MB device with about a 800x480 or less screen.
This is mostly intended to be used by apps to determine whether they should turn
off certain features that require more RAM.
