Jesse,
Does the Stratus 2 add much beside expense? It appears the Foreflight includes most of the features of the Stratus. Please fill me in why one would justify an extra $800 over the $75 Foreflight?
Make sure you understand what they are and what they do. As others said, there is plenty of information out there but here's the simple bottom line:
Foreflight is software. And app that runs on an iPad.
Stratus is hardware, a unit that provides ADS-B (weather and limited traffic information) and, in the case of the Stratus II, altitude and heading data.
Foreflight and Stratus have an exclusive relationship. The Stratus hardware only works with Foreflight; the only ADS-B unit Foreflight works with is Stratus.
Foreflight without Stratus will give you relatively* current weather information
while on the ground. Foreflight with Stratus give you relatively* current weather, plus some traffic information,
while in the air.
If you don't care about in-flight weather, you don't care about having a Stratus.
(*relatively current - weather, particularly NEXRad data being provided, whether on TV, over the internet, or by ADS-B or Sirius/XM) is subject to delays. You can't say that too often)
