The New York Times’ David Pogue is to tech reviews as John Madden is to play-by-play commentary. Both are legends, and both can be a little wacky at times. (Seriously, check some of Pogues’ videos. The man has no shame.) So when he gives some tech gizmo the thumbs-up, you’d best pay attention. Such is the case with the Eye-Fi Explore, an SD card you plug into your digital camera with built-in Wi-Fi and geotagging. Geo-what now?

The card, which costs $130, lets you upload your photos to Flickr and other such photo sharing sites from wherever there’s a Wi-Fi hotspot. No need to whip out the laptop simply to upload a couple drunken night out shots, then.

But even cooler is geotagging. Every photo stored on the card has its physical location embedded inside. It’s not quite GPS, but a close approximation called WPS, or Wi-Fi Positioning System. Anyway, once uploaded (or edited on Photoshop or whatever), a map will display where the photos comes from.

For example, if you take a photo of you and your girl by the Statue of Liberty, a map will show up on the computer showing Ellis Island. Definitely handy for those “where were we when we took this photo?” moments.

The WPS isn’t 100 percent accurate, but it’s pretty damn close. And when you think that Eye-Fi somehow managed to cram all that Wi-Fi wizardry into a small SD card, it’s all the more impressive.

One of the more clever devices out there today, no doubt.
