Pebble definitely doesn't waste any time. Pun totally intended. It was barely two weeks ago when it put its color-toting Pebble Time up for grab by non-Kickstarter backers. Now, due to popular demand, and we'll just presume it is really popular, it is doing the same for the steel-clad Pebble Time Steel. With an important caveat. This isn't the start of retail availability of the new smartwatch just yet. Instead, Pebble is only taking reservations on its website, with a promise to start shipping sometime in September.
