Not only are they of
dubious usefulness (and we strongly recommend against using them), but most task killers will also dump the cache files of applications they are busily killing off — which means when you go to use the app again you'll need to download the data all over.
Between MAR and BPL we have 8 of 17 posts unnecessarily insulting, and an incredible 13/17 of

(Of course it's still a smartwatch, a product category of
dubious usefulness to the broader population, but that's another story.)
