I've been using TB for personal and work since it's first day and never hit the bug. I've never known any co-workers to hit the bug. I'm sure plenty of other software that we use every day has similar severe bugs that occur just as infrequently.

I'll keep using TB. I'll also make sure to look both ways when crossing streets and won't assume that cars are going to stop for red lights because my chance of getting hit crossing a street is more likely than getting hit by this bug.
