You've been lucky - I've been turned down for positions I was otherwise qualified for because of "too many job changes" (and yes, they told me so). I've also seen hiring managers (from the other side) not even consider resumes with too many jobs of too short a duration. I don't think it's the kiss of death, as long as you're competent; I've never been out of work, in spite of a four-year period where I held four different jobs, but it's worth keeping in the back of your mind.
