moving away from the traditional CAA charts
Regardless of whatever electronic solution you choose, you might not want to do away with the traditional paper charts anyway.
It can be debated whether having paper charts on board is still legally required if you have all the information available electronically (with backups as appropriate), but it is certainly a good idea.
Me personally, I'm not leaving the ground with an appropriate set of paper charts within reach. Despite having a panel-mounted and multiple hand-held GPSs with me.
