My choice: SN-10 as primary glide/task computer/vario (with it's own
dedicated Garmin hockey-puck GPS hardwired in). Backup (on separate
battery system) is my IGC logger (a Themi) driving a PDA running
SeeYou Mobile, used mainly to show airspace, the current task, and
reachable airports (and ridges if useful).

SN-10 map page is OK as a backup but does not approach the utility of
the PDA display. SYM allows setting up a simple easy to see moving
map with nice big fonts and easy to see lines - visible even in bright
Arizona sunlight.

PDA also can download the logger files from the SN10 and Themi (via
appropriate DOS emulator software - a bit of a pain to setup but does
work).

302A look nice but too expensive for a backup vario. If i win the
lottery, though, it would replace the Themi and have the advantage of
a TE vario that doesn't rely on the vulnerable TE probe.
