Aahh, the benefits of the nicely walled garden for the iSheep.
On my Android phone I run of course XCSoar.
A fully functional flight computer as a backup, not just a vario.
And my Moto Atrix is very readable in sunlight, even better than my
Ipaq310.
If I need to switch to the Atrix early in flight, I just plug it into
my USB outlet for power, to avoid the battery running out after 2-3
hours.
And finally, I like the larger 4' screen size on the Atrix.
