And a little later:
The Techopedia site has a definition for fondleslab that goes like this:
"Highly idiomatic": ya think? Subsequent discussion on that page notes that many people think that the term is "extremely informal and not appropriate for business use" and that it is used in journalism. Indeed, that's where our examples come from, and indeed, The Register seems to be the most avid user of this term. Urban Dictionary, of course, has a definition (essentially the same as this), which somewhat unexpectedly also includes an entry for the term tablet-widow (echoes of, for example, golf widow.)
The, um, informal nature of the term pertains, of course, to fondle. This is technically a neutral term ("touch or stroke tenderly"), but it's used so often in sexual contexts that it seems to lends a certain impropriety to the term's use elsewhere. Like here: it suggests an unseemly attachment to the device. To my mind, anyway.
I can't imagine any context in which fondleslab would be considered a neutral term, let alone a positive one. For example, I would never consider my own devices to be fondleslabs. No, that's something that other people have. :-)
