I intend to buy this device primarily for reading pdf magazines secondarily for digital art. (i know comics fit the screen perfectly in this tab), but then is it comfortable to read pdf mags(4:3) on this 16:10 tablet in both portrait and landscape mode without zooming in/out, scrolling ? does it occur gaps at the top and bottom especially in portrait mode ?

secondly, are there any other graphic apps as good as clip studio but without a subscription fee ?

thanks
