I am also a professional developer who uses the software you speak of. It's better in every way compared to AIDE and is intended for enterprise customers (that's why it costs so much). It's impossible to compare prices because enterprise software is never in the same price range as consumer software. A better comparison would be to compare consumer software to consumer software. A scenario could be VS2010 Pro, which is $400 (unlike VS2010 Ultimate, which is $11k). Even in that comparison, VS2010 is far and above a better software developing solution than AIDE. Further, you need to look at the market it's being sold in. Roughly 60% of apps in the Android market are free, and less than 1% of apps are more than $3. Compared to other viable alternatives to AIDE, AIDE is expensive. You're essentially comparing apples and oranges, which is a terrible thing to do. The PC software market and mobile market are so different than one another (please find me $60 Android games, for example. Or, several hundred dollar Android software. You can't because it doesn't exist).
