Great ideas. Flashlight capabilities.
The blu one already has that... sort of. When you screw a battery into it, this INSANELY BRIGHT BLUE LED on the side lights up to tell you it's charging. Seriously, I leave the pack on its side on the table and there's a big blue circle on the ceiling of a well-lit room.
By the way, sign me up, too, for a better 510 PCC. Ideally I'd love one that basically echoes the blu pack, which stores a completely assembled cig, an extra battery (full or charging), and five carts, which I empty out and refill with five different Johnson Creek juices and leave attached to extra atomizers. I know blu catches a lot of flack, and rightfully so on most counts, but the pack seems pretty well thought out to me (aside from the unintended flashlight behavior).
It operates really well one-handed-- I typically flip the lid up with my thumb, grab the cig with my teeth, pull it out, then flip the lid closed again, support the cig between my fingers, and draw. I'll likely stick with the blu for out-and-about time until I can find a better e-cig with a PCC that works as well or better.
Actually, I'd love a decent PCC for the DSE8084 for when I'm on the move, now that I think about it. The one at East Mall seems to have the same basic limitations as the 510 one: holds/charges one battery, holds one atomizer and six carts. Meh.
