...and the rest
Ok, this is really, umm, well, err... you decide for yourself. Gizmodo has the enhanced scoop. The Stokke Xplory is the latest high end stroller to hit the streets. At around $800, it has got to have a serious pitch. And it does, sort of. As you can see from the heisted image on the right, the seat can be brought up high so that your kids can be further away from dust and exhaust fumes. (Someone bring in a physicist on this... I'm not so sure about the fumes.) Sonja says that it is kind of cute - but it is eight hundred dollars cute? Ok, now she says that it sort of looks like a cheap office chair.
Update
I found a better site for going through the Xplory features. Very well thought out!
