I wonder if even here, this is still true for most developers these days. It seems that Google Play is flooded with developers these days, and it's hard to get anyone to see your game without the same kind of marketing needed on other platforms. With the exception of some hold-outs like Nokia, making significant money (i.e., comparable to full time job) from mobiles for Indie developers seems it would be as hard as it is on non-phone platforms. (My games get more downloads now on Windows than Android, though Symbian still leads by far.)
This kind of thinking shows me you aren't willing to make good business decisions and let personal feelings interfere. That is deadly and you should re-think why you wouldn't enter a market where a game can take 2 - 8 months to make and is becoming the biggest profit margin for game developers. IMO It's a lot easier to monetize iPhone and Android games compared to almost everything else (Maybe barring web games).
Making money on games is always hard, The advantage of mobiles is in the format, you can push out one or even two good mobile games and get some decent marketing for them with a $100k budget. On the PC as an indie you pretty much need to hit a neglected niche to be able to compete on a small budget. (There are quite a few of those to choose from though but MMOs, FPS:es, Action RPGs, etc aren't genres you want to aim for unless you got a cool twist up your sleeve to be able to get by with far less polish than your competitors)
