Your tech quest history is more Sad Mac than Happy Mac. Reboot with a visit to new virtual techie-toy shop, Grand St. Every other day, the site adds a new plaything to its rotating roster of creative gizmos. That means futuristic thingamajigs like Livescribe Sky (a Wi-Fi-enabled pen that digitally transcribes handwritten notes); stylish, self-watering Click & Grow planter; and the hand-powered BoostTurbine cell phone charger. Products are fully vetted and tested before making the cut (read: They’re functional and fun). The state-of-the-art experience doesn’t officially launch until March (Sad Mac). Fortunately, we pulled some strings: DailyCandy readers can shop the beta site now — with a $15 credit (Happy Mac). Items are shipped the same day. Go, go, gadget. Available at grandst.com, $15-$450.Photos: Courtesy of Grand St.
