"On the downside, being a mini-tablet it was too big for most pockets "
How small are your pockets? My S4 fits comfortably into my shirt pocket with nothing sticking out. I'd have to bend 90 degrees at the waist to risk it tipping.
Also, don't use the Samsung generic keyboard. Gingerbread Keyboard is free, better and comes with the predictive text we all crave - though for some reason its first suggestion for "di" is "dildo". So don't take too many shortcuts when typing "didn't", or your texts could become a whole lot more fun.
Mine is, of course, the one with the Galaxy S4 in the pocket.
