I have no reason not to believe you, or to care at all really. All I know is that I do hours worth of browsing on Chrome on my iPad everyday (even right now) and I can't recall ever experiencing a crash. Sometimes there's no explaining why some people have problems with certain software and others don't.
Just to back up what I'm saying, this is the very first review in the app store for Chrome:
And out of the next 25 reviews, 6 say it crashes all the time. So clearly this goes beyond a handful of people.
