I should add one more thing. In terms of taking smoothies on the road, I cannot say enough good things about my Big Bubba insulated mugs. They're 52 ounces, so each one holds a whole pitcher of smoothies. They have little flappy things that lock into place and prevent smoothie from spilling out, in the event that the cups flip over. (I have tested this. 45-minute drive to work with smoothie on its side. None on the car carpet. None.) They're stainless steel outside and BPA-free plastic inside. And the mug is big enough that you can get your whole hand inside, for super easy cleaning, in case you don't finish a smoothie and it starts to ferment and stick to the sides. If you rinse the cup out as soon as you're done, just a plain water rinse is plenty to get the cup clean. Smoothie doesn't stick to the sides, unless you let it sit for quite a while, and even then, a wipe-out with a paper towel or sponge works fine. And the cups are insulated, so they keep things cool for hours. Poifect for my purposes.
