In what appears to be a race to the bottom in terms of price and quality, no matter how this impinges on the quality of learning, the prize today goes to the Teachmate PC.
Resembling an oversized Tamagotchi, the device features no keyboard, no touchscreen, no Wi-Fi and virtually no software.

The software it does have, maths and reading, are $20 a pop (per device) and the syncing and charging case is $300 (for 30 devices).
In short, it's a piece of future landfill that looks like it was designed in a coffee break.
The use of the word "PC" must be one of the most cynical marketing ploys yet for a not-for-profit company calling itself "Innovations for Learning".
