I use an iPad mini, which is much more manageable in the cockpit.
I have a yoke mount and a suction mount. Most of the pilots I know use the same kind of mounts, whether for a small or large device.
I have tried knee-pad mounts and the front seat, but in my experience, having the device within your scan is much more useful and less distracting than having to look down/sideways. Doubly so if you are flying on instruments, where there is the potential issue of leans/vertigo.
