I've ordered hardware from vendors numbering in the double digits and you're only the second to speak to me personally. That means a lot to me. (PM me for the name of the other one, I'm not going to mention it in Buzz's forum).
Back on subject, I was really interested in the Infinity, it's smaller and sleeker, more like my current preference (eGo) so I was really into that...but the forums really turned me off of it. It's a double-edged sword that way.
One of the things that turned me off was the battery life (6 hours vs. 7 hours on the buzz). So if you can double that, it's a no-brainer for me. 12 hrs vs. 14 hrs it doesn't even matter at that point, I just want it go a full day's work.
