As a reminder again: the battery is limited, very demanding applications will keep you running 30 minutes and less. You will need a battery extender solution of any kind.
Apps very rarely are even free, or cost mostly between 5 and 25 Euros. Some big new blockbuster releases may cost more. But these are not what I am interested in. The bundled Asgard 2 game for example looks extremely impressive, and it is big - but its not my cup of tea, unfortunately (and blocked one third of the memory), so I deinstalled it again.
