MLP SMS Text Messenger at Toys"R"Us

These SMS Text Messengers have been out for a little while at Walmart, but this is the first time I see them listed, and Twilight got her wings on the new version, so let's dive a little bit into it.
First of, the name 'SMS Text Messenger' is a bit misleading. As these do not actually send SMS messages (at least not over regular networks) and don't require SIM-cards to work. These actually send little text messages to each other wirelessly with some kind of technology (probably infrared) over a short distance. From the Walmart comments we can read that this short distance is around 10 feet (30 meters). The new Toys"R"Us listing also mentions that it can hold phone numbers, addresses, emails and memos. But don't expect to be able to have phone calls and send emails, as these can only text each other and hold a few notes. Looking at the keyboard it also seems to have calculator features and sound.
The only real purpose behind these is probably to secretly send text messages to each other in class or at parties. But besides that, it looks kinda cool to have an MLP 'phone' that can actually send messages.
