I have been using Sauce Labs the last weeks evaluating if we can use it for our CI process and during this weeks that is what I have found:

Pros: * Easy configuration, our tests are in Ruby and we only have to add a small file with our credentials to everything works as expected. * Good integration with Jenkins and Bamboo. Nothing to do except a curl to update the apk/app * Video on streaming * A very good log system

Contras: * Only emulators * Slow start, I missed an option to run the tests without video to run the tests faster * I missed a window to manage the files I uploaded.
