yeap cant wait to try the 4.0! I wonder which device will take over as my daily user though. ive burned twice since the 3.0 arrived and hated the pipe both times. im strictly vapor now and if I haaaave to ill use a 2.0 but thats my worst case now. I wont even touch a bong or pipe. tastes nasty to me now. im a vape snob.....lol not wonder the early reviews on 2.0 vape were poor but at the same time those people also said it was a great burner. if it had been marketed as a burner I think it would have done real well
