Do you ever see something and think "Of course, why did I think of that!?".
That's how I felt when I saw this cool Wifi Detecting wristwatch. Why would anyone carry around a wifi detector when it could be seamlessly integrated into an attractive looking wristwatch. In case you're not familiar with what a wifi detector is, it basically looks for WLANs nearby to save you having to fire up your laptop etc to check.
So this is a very smart design idea, I think - what do you reckon?
They cost about £20 quid from I Want One Of Those and could be an ideal gift idea for the geek in your life this Christmas.
