To chime in with Budzman and other WeMo users, My cloud has been on and running 24 hours, most days, and has been on for 24/7 stretches, weeks at a time. I agree on the theory of repeated heating / cooling cycles having a negative effect on the internals, especially the soldered leads. I also will have to say, the temp of the Cloud externally, kind of peaks at a point, and it no longer gets hotter and hotter. Also, as several Vets here have mentioned, keeping a fan as small as a little PC case fan, to anything larger, pointed towards the Cloud makes all the difference in the world! It keeps the air moving, and the heat dissipates incredibly well! But, unless it's an issue for holding the unit, and wristbands won't solve it for you...a small fan isn't necessary at all...just a huge help! Either way, my Cloud has been on nearly 24/7 since sometime back in aug./september/october when the WeMo first got mentioned here. I wasn't the first, but one of quite a few people who decided to jump on the idea...it's been a life saver ever since! The ability to turn it on before leaving work, have it come on on a timer in the AM, or do like I do and have it on 24/7 when home, and only off while away for long periods. It's great if I have to wake up in the middle of the night because I get sick, and the Cloud is ticking away, waiting to help me!
Back on topic though. I was visiting a new friend yesterday, and I brought the Pax so I could medicate while I was there. (I only bring the Cloud to certain places, knowing that it will be safe, etc.) I'm always wishing I had the Cloud when I'm using the Pax, but it works quite well when I need it. Still, I'm so excited about the quicker heat up and removable cord on the new unit, as this will solve one little issue that usually keeps me from bringing the Cloud with me. Now, I can use it in an environment where I would usually feel unsafe about the cable being exposed, and the unit potentially getting yanked. Now, I can heat it up, and unplug when I want to pick it up for a hit, setting it back in a safe spot to keep hitting afterwards. It's going to make passing it around easier too, in those situations with groups, etc.
So, as far as this whole potential option for two colors...and having to choose! This suddenly became more difficult! hahaha, at first, it was just wait...now, I have to make a choice! I don't know what I'd do if I could afford one of the packages with glass, and had to make a decision on mouthpieces and or perc styles!
What a great time to be a vaporist!
But in all seriousness I think I'll go with the black unit if given a choice between black and white. if it's down to black and another color, it would have to be green to win me over (always been my favorite color). I just love sleek black electronic products. I decided to strip my units paint a while back, after determining that it was solid enough to not die, and unlikely to need to be sent in for warranty before it expired...I regret it, because I miss the black with the silver inner shell. And, this unit gets significantly hotter IMO without the paint. So, I'll be getting a Black Cloud EVO more than likely, if given the choice.
