This is a very niche product. It is a dual language (Japanese and English) device that is a dedicated text editor. It runs off two AA batteries (I'm supplying two alkaline batteries to get you started, but rechargeable batteries work fine too). A pair of batteries will last dozens of hours of use. Files can be saved to an SD card (provided), and can be transferred to a computer via the SD card or a USB cable (provided).
Drawbacks: (1) the device recognises only files with a ".txt" extension (so it is no good for editing, say, ".xml", ".cfg" or ".java" files); (2) the keyboard layout is not quite UK standard for punctuation symbols, and is not quite full size; (3) a backslash symbol is always displayed as a Japanese yen symbol (¥).
Since this device is intended for distraction-free writing, it does not have any games or internet access, and it is not possible to install any other applications. If you are unsure whether this device will be suitable for your needs, I suggest doing a Google or YouTube search to find more details of it.
My schedule is unpredictable but reasonably flexible at the moment, so let me know what days/times suit you for collection and we can work it out.
