I initially had some problems with public transportation, and this was mostly based on the fact I dislike crowds. I didn't feel comfortable, especially during rush hours, to be surrounded by all these people, all the noise from them, etc. I felt like a piece of tuna in a tin.
But when I was using the tram or the metro to get to my job, I sort of got used to it, and it soon barely even bothered me anymore. Nowadays, I even quite enjoy using the train. I use it a lot now, because I travel around the country a bit more than I used to. I make trips to cities and everything. I think the train is very comfortable, and, perhaps because I don't use it daily like commuters, I barely notice any delays or unpredictable schedule or something like that. When I was using the metro to travel to work, it barely ever let me down either. So I'm quite pleased with the Dutch public transportation.
I should add, though, that whenever I visit another city, I tend to walk everywhere, preferring walking to taking the bus or the tram. Even if it's a lot slower, it gives me a bit more freedom to walk, and I get to look around me a bit more so I can take in the sights.
