Jealousy I imagine....some people seem to think that if they don't have / can't afford one, then they must be rubbish, and do the best to put them down. I'm sure Sigmund Freud would have a theory.....
I don't have one / can't afford one, but I reckon they're a real step forward in GA, and IF I could afford one, I would have one (well, maybe I'd have a TwinStar instead, but thats just because I like twins
)
