I've had my Pilot for about 2 weeks now, and love it. I'm now using cartridges only when I'm out & about, and have been dripping on the atomizer when at home. Dripping works pretty well, but can get messy if I'm not careful, and it's near impossible if I don't have good light like when I'm watching a movie.
Last night it dawned on me that the only reason people started dripping was because the older models have a recessed atomizer. With the 401, the atomizer bridge sticks out, which makes it really easy to dip it in eliquid. I put maybe 10 drops in a shot glass, and just dip the atomizer into it. It gets the perfect amount of juice on it every time, and there's absolutely no mess.
I think a perfect solution for dipping while on the go may be a contact lens case. You can get them for maybe a dollar at about any convenience store, they should hold about the right amount of liquid for dipping, and they are designed to hold liquid without leaking.
I did a little searching, and they have contact lens travel cases that hold the lens case, tweezers, 2 small vials, and the other side has a compartment to hold glasses (which I would modify to hold batteries, atomizers, and cartridges). I think it would be the perfect carrying case for the Pilot. I can't post links yet, but search for "Contact Lens and Glasses Case" on ebay to see what I'm talking about.
