This is Ground, the maker behind some of the most clever iDevice storage and accessory options out there, is back with the most ambitious project yet–The Mod. The Mod starts as what looks like a simple leather folio for your iPad Mini. On the left, there are places for your business or transit cards, a charging cable, and a phone. On the right, a spot for your iPad Mini and another slot for a stylus. Everything zips closed, and there’s even a carrying handle. But the real magic is the interchangeable inserts that magnetically attach to the center of the Mod. There are 10 different inserts in total, with storage options that range from Designer (eraser slot, pocket notebook holder, headphones) to Traveler (multiple passport slots, space for boarding passes) to Musician (pick, capo, string storage) to one that includes a 4,500 mAh battery charger. If your needs change, just pick up a new insert. It’s brilliant.
