There's a learning curve, but it's not that bad. The biggest constraint is that you are in a very limited "world" in Arduino land, it's very systems programm-y. You don't have a proper OS, you don't have a filesystem. You don't have near unlimited resources. Depending on the chip you use you may have a small amount of RAM. Also, arduino enforces a basic structure on you of having setup() and loop() functions. Once you get used to it it's fine, but it takes some experience to get the hang of it fully.
