It works

Downloaded Sept 12, 2012 to new iPad.

Pros:
+ No crashes so far :-)
+ Supports several online sources for TLEs or manual entry
+ Sliding timeline, but wish there was a quick way to reset to zero.
+ Can show several tracks with good zooming ability
+ Can alert to future passes
+ Earth map, or local horizon or zenith views
+ Supports multiple station locations

Cons:
- Dont yet see a way to show footprint
