I‘m hapy with my iPad Air. For W&B and performance planning I use the Gyronimo Apps, for wx and Notams I just download the information from the official webpages.
Sky-Map is helping me to get from A to B and if needed you can add „real time“ overlays (radar, wind etc).
I think a tablet is a big contribution to safety. Instead of staring at the old fashioned paper chart for hours trying to figure out where the last known position of my finger was, a glance on the helicopter symbol on the tablet is sufficient to know exactly where I‘m at.
Consequently, more time to look outside.👍
