I replaced the Cambridge L-Nav, GPS-Nav, electric vario and LCD navigation display with an LxNav S80 and Nano (the S100 wasn't available at the time). I believe the biggest advantage is that it simplified my instrument panel -- three instruments on my panel (and the GPS recorder behind the seat) were all replaced with one 80mm instrument. I have flown with the S80 for two years now and am very happy with its performance. If/when I add Flarm, the S80 will display that information as well.

The S80/S100 also have a nice moving map display for navigation, so you can ditch both of your tablets. Less things to look at inside = more time to scan outside for thermals and traffic.
