Just as a heads-up, we try to avoid subjective questions, as per the FAQ
What kind of questions should I not
ask here?
Avoid asking questions that are
subjective, argumentative, or require
extended discussion. This is a place
for questions that can be answered!
Now you are new, so it's OK :)
In terms of your question, I would say:
- Who gives a crap if its hard, if you want to do something, roll the sleeves up and do it, the harder it is, the more rewarding it will be!
- I'm not a Symbian OS dev (once I get a PDA I may get into .NET CF), but I would say that mobile apps are really starting to pick up, many apps are now being released with a mobile app to keep people connected and using your software. The more people using it = more business!
- Looking at the Wikipedia page here I would say there are plenty of options for IDE's and platforms to actually developing against, awesome!
