Has anybody bought the app Sibley Birds of North America for their smartphone? I of course have the book, but never take it into the field with me. I downloaded the LITE version as a trial, but it is very limited in what it has (30 species vs. 800+ in the full version). The full version is $19.99, pretty spendy for an app. Has anyone bought it and do you find it as useful and easy to use as the book is?
