You can get away with using the String Class with some care taken.. usually.
Problem is that many people don't know there's a reason to take care until it bites them, and then they post about a problem with crashes. You don't see many posts from people who managed to stay within limits, like the 2K RAM limit.
We will see a lot of this forever. People who learn C++ on PC's generally don't learn C strings and have no clue what goes on in the magic box let alone why a smaller box should be different.
