Among the ATAP initiatives that have been announced, one in particular is quintessentially Google-y. It’s Project Ara, which aims to reinvent the smartphone by breaking it down into modules that can be assembled and customized in a limitless number of configurations. The company first disclosed that the project existed on October 29 of last year, when it released some intriguing photos but little in the way of concrete details. Today, it’s lifting the veil further as it prepares for an Ara developer conference it’s holding at Silicon Valley’s Computer History Museum on April 15-16. A year or so from now, it hopes to have a product on the market.
