Im on my seconde CB.
They work like an Android pn, but not as many or good apps.They are not like a tablet.
They can have storage for docs and such, and some are expandable.
They are good for browsing.
Docs can be saved to numerous "Cloud" type storage providers...but docs can be wonky on different ones depending on the programs used to make them.
Both the ones I had, have automatic updates for security. Only need to restart and they are in effect.....thats about the only thing I like about them.
They suffice. BTW them, tablets and phones, I haven't touched a windows computer in about 8 or 9 years....I do miss them for certain things..
