Dyson's latest stick vacuum is impossibly thin and lightweight - but is it worth it at $599?

ZDNET reports that Dyson’s new PencilVac, a $599 ultra-thin cordless stick vacuum with a 1.5-inch-diameter handle and integrated dustbin, is now on sale, featuring a compact high-speed motor (up to 140,000 RPM, 50 AW suction), Fluffycones for tangle-free cleaning, bidirectional illumination, and a lightweight design for elevated areas; competing lightweight cordless models are expected later this year.
