user4143: A simple one really: 

What is the most important thing you look for when choosing an Arduino-compatible development board?

Do you even look for anything specific, or do you just automatically plump for the "default"? Is there any specific feature set you need? Is size important? Price? Processing power? Memory? IO pin count?

user37622: I search for maximum features I need for the project and minimum features I don't need.

user6936: If it is an Uno or Mega, then I try to ensure (by checking with the vendor first) that it doesn't use a CH340.
Many vendors show an image of a standard Uno/Mega with a 16U2 but when it arrives it's got a CH340(G)... which are a right pain when working from a Mac (even though I do have PCs as well).

user57111: I look for documentation, such as on-line specifications, including a datasheet with detailed specifications, pinouts, and sample circuits/implementations.
