I do have one (no I haven't sell it on ebay 😉 ). I used it until yesterday. I changed because it doesn't hold the coffee hot long enough. Now I have a thermos one with a closed top *hint*.
Once I left coffee in it before going to vacation. There was a whole ecosystem inside when I came back... I would have needed a Biohazard sticker 🙂
I've got one! It was "diverted" from the box they were shipped to NI in, thus depriving a likely more deserving member of the community at the time, but proving to be a cherished relic of my NI days. I had some hot chocolate in it last week.
I too have received one. When the NI guy told me "I've something for you" I thouht to some documentation on new hardware or something like this. Then he went and took out the mug from his bag: what a surprise! 😮
You know? This mug has really made me a member of this community rather than simply a user of some product! 😛
