Do you hate going into a coffee shop, opening your laptop, and booting it only to find the supposedly free WiFi is crap? I do too. Fortunately they’ve taken WiFi detectors and stuck them inside watches, so you can check to make sure before you go to all that trouble. You can also use it to find the optimum spot for hopping on the neighbor’s WiFi, if one were so inclined. This sweet baby retails for $39, and I predict will be as popular as those calculator watches were when they first came out.
