For those who have everything: Origami

Press a single button on the Origami and this “sleek and stylish” stroller uses battery power to rise from a crouch to full attention. Once you load a toddler in, a built-in weight sensor will keep the pram from folding prematurely even if you hit the fold button by accident. Generators in the wheels supply juice that also powers undercarriage pathway lights and a dashboard with its own odometer, speedometer, and thermometer. If you purchase a $40 add-on, the stroller will even charge your cellphone.
