I wish someone would write a soaring book on flight computers. How to choose one, program, trouble shoot them, use them. Combine book with YouTube explanations.

I wouldn't expect a "Consumer's Guide" of flight computers to be published any time soon. Researching out internet forums on which flight computer system is best will get you a great deal of biased information. Everybody has an opinion.... and, of course, theirs it correct ;-)
I would suggest that you download all the popular flight software simulators and decide for yourself which is best for you. After choosing which program you like, decide on the hardware that best suits your needs.
This will take some time and effort on your part, but I suspect the results will make you happy!
Good luck.
