Wasn't just me though, several friends of mine have tried it and they all say the same. Games just are not the same again without the TrackIR. For instance i loaded up Arma2 accidentally without running the TrackIR sotware and i felt like a blinkered horse on a railway line! It was just bad lol
My experience was the same, but that does not mean that anybody who says they couldn't get on with it is wrong or talking rubbish as you stated.
