yes i have a 3 wheeled pram - none of the wheels rotate.
it's not so bad, you get used to it. i admit if i had to buy another pram though i would go for a swivel wheeled one - i didn't really think much about it at the time when i was buying one though. silly me.
in my opinion, the fixed wheel ones are somewhat sturdier - you don't get the wheels going dodgy like some swivel wheel ones do, but it is harder to manoever.
