“If you are choosing the A+ for a project you probably know a bit about the pi already however I urge you to be very careful and choose wisely. Can you go the extra £10 for a B+?. Can you do without certain benifits should your change the project later.
In addition Ive found compatiability problems abound, developers not supporting it through either hardware issues or software packages being developed for other incarnations PI but not tested for the A+. My advice is to leave a few months until the community picks up as it seems to be a bit more slack in comparison to the release of the zero W or B.”
