Finally. No more walking into a coffee shop, unpacking the laptop, waiting for it to boot, only to find out that they don’t have Wi-Fi or that the signal sucks so badly it isn’t worth the bother.

Instead, just grab your Wi-Fi detecting t-shirt from the laundry pile and you can instantly know where the best Wi-Fi spots are in the neighborhood.

Now all they need is a way to indicate whether the Wi-Fi signal is open and free or encrypted like the annoying AT&T one that so many places seem to be using these days.
