Thanks, everyone, for all the response, links, information, and input.
A supply of various sized laptops is not a problem with us as I have several that I have saved from dumpsters and resurrected after relatives have had some minor issue with them.
I fixed up a couple that were no bigger than an iPad and gave them to some of the kids to play with; maybe I will hang on to the next one I get.
There are times, however, when a laptop is just inconvenient for one reason or another and it would be nice to have something small to back-up the memory cards onto.
Until I saw the post that prompted me asking about them, I was not even aware that such a thing existed.
