Well, I did finally find something it can do!
Hooked it to the 42" HDTV in my PC shop. It seems to be good for watching The Twilight Zone on YouTube.
Still worth the 25 bux.
At the end of the day, Jim, if you can make use of the tablet and enjoy it, then the 25 bucks was well spent. When I was offered the RT Surface for 20 bucks, I had already ordered a dual OS tablet with Windows 10 and Android, so it was not a device I needed anyway. However, if I'd had a use or two for the RT tablet at such a low cost, I may have been tempted, despite generally preferring a full Windows device.
Currently I have 3 tablets: The HP 2-in-1 with full Windows 10; a Teclast X80 Pro with Full Windows 10 and Android 7; an el cheapo with Android 5 on it. I used to take the HP 2-in-1 and the Android tablet when I went out, so when I saw the dual OS one with Windows AND Android I snapped it up so's I only have to take the one tablet with me. Besides, the HP 2-in-1 was a real tight fit in my manbag anyway.
