Keep in mind a 7inch tablet is something you might be
able to slip into your pockets, (if you wear cargo jeans )
unlike those Tablet In Name Only things that beg for a backpack
and all the hassles turnstile goons put people through these days.
(8inch is just a tad too wide, unfortunately)
And a properly discreet bluetooth keyboard can be useful
if you need to type more than a paragraph...
