That travel mug looks all very well except there's no way it would fit into any cup holder in my car - the handle would get in the way. Unless it's actually a foot tall and the bottom fits into a cup holder ;)

One thing that bothers me is plastic stirrers when you get a take-away coffee. I've heard from a couple of sources that the coffee is definitely hot enough to release nasties from the plastic. A little wooden stick is better; the barista stirring in your coffee is best - after all they generally use a metal spoon and don't use the little paper packets of sugar. The only downside is they often use that useless white sugar instead of raw sugar.

We coffee fiends are a picky bunch aren't we? :)
