870 on XO1

[Kevin Gordon]

dsd:

Yes sir, 860 behaves just like 870 in identical comparisons in terms of time
of booting and activity launching, just as you predicted.

However 860 leaves the completed boot animation circle up, instead of
turning the screen black for that rather long period of time between
animation completion and the appearance of the favourite wheel.

Guess I had just gotten used to (and happy with) the quicker osxx series of
builds.

Cheers,

KG
