All I can say in absolute honesty I have zero bias in either direction. I haven't even really checked out jet yet. I glanced on their site for a few minutes(had an invite), and never ordered anything yet. Just by reading through this thread both yourself and yuneeq seemed to be overly defending them. The people bashing them seemed to have had legitimate issues.
Should I tell you something Dan ordered a laptop for $100 he thought he'd make $600, at the end he got a monitor, this was in the first days of their beta, I personally know someone who got $25 JetCash for such an incident "recently" which means they are getting better,
Personal experience: On the third day of their beta (May 2) i found a tablet that would normally cost $750.00 at just $6.65 I ordered 5 of it (that's all they had listed), the real product almost shipped (I know that) but at the end they caught on it an canceled my order.
