Hmmm...
The Pax is amazing, for sure, and is my favorite portable--it's really no contest relative to my other portables. Yes, I'm lucky to have some very nice home units too, though the past few days I've foregone some Cloud sessions for a quick Pax rendezvous because I'm still so amazed by it (on the Honeymoon, if you will). I mean, it's like sorcery or witchcraft...OR BOTH!!
But...I received my Cloud just two days after my Pax (and on a Friday to boot). So, as you can imagine I've been hard pressed to put my Cloud down (and I've been in a vaped stuper). The Cloud is truly mind-blowing and if you ever get the $$, I advise you take the leap. (while you didn't mention it, I'll note my viVape delivers taste and clouds that rival the Cloud. Though the Cloud is winning so far in overall coolness, ease of use, and getting me baked to ancient Byzantine.)
Regarding my HI, well, what can I say. It's made just for me and is very special to me. Not to mention how freaking efficient and effective it is. I can say with confidence you made the right move in getting on Alan's waiting list.
My summary: If you were to own the Pax and the HI, you'd be all set. That's just me. I don't want to hijack the Pax thread any longer, so feel free to PM me if you like.
Edit: Hey! I found party mode just now while Paxing out! Parrrrtaaayyyy!
