This cheap device is also touchscreen. Only single point though - no idea if Apple is multi touch.

Apple Watch is multi-touch, if you hold two fingers on the face, it announces the time.

Which relates to the cost and battery life of the Apple Watch, it's a mainstream device that many people with varying disabilities can use. It has a full-fledged screen reader in its operating system, in addition to the development costs to support multiple interaction modalities, some will not be achievable with lower-powered, less specialized processors.
