I flew with PDA only for a few years before adding a SN10B, to me the SN10
is a big improvement. The display is *always* readable at a glance, it
*always* works when I turn it on, and there are *no* settings to fiddle with
before take off. I now use the PDA as a moving map and the SN10 for
everything else. I hardly have to touch anything on the PDA or switch pages
at the SN10 during flight (XC, no competition flying), the same would be
true with a Zander, LX, or any similar system.

After landing I use the PDA to read my flights from the logger to a memory
card, so no need to bring a laptop to the airfield. I guess (but haven´t
tried yet) I could also use the PDA to transfer airspace and waypoint data
to the rather small (compared to a PDA) SN10 memory.
