We've seen it put its processing power behind the iPad 2 and heard rumors of its presence in the upcoming fifth-gen iPhone, but could Apple really be considering putting its mobile-minded A5 processor in a MacBook Air? According to Japanese website, Macotakara, a trial of the ARM chip is already underway. Apple's reportedly been experimenting with a Thunderbolt-equipped MacBook Air with the A5 on board, and "according to someone who has seen a model running with [Apple's] A5 processor, the performance is better than had been thought." Two weeks ago, we reported on rumors that the upcoming MacBook Air refresh could be on its way as early as next month, featuring Intel's Sandy Bridge 17W mobile processors -- a claim we'd say could hold water. Of course, this information has trickled a ways down the grapevine, and the presence of an A5-packing test vehicle doesn't mean much anyway, but you can consider our interest piqued, regardless.
Pentax's Optio WG-1 GPS point-and-shoot satisfied geotaggers out of the box, but owners of its K-5, K-r and 645D DSLRs have had to make do with third-party taggers like the PhotoTrackr or Eye-Fi. The new hotshoe-mounted O-GPS1 module fixes that oversight by recording latitude, longitude, altitude, Coordinated Universal Time and shooting angle. Everyday snappers might find an extra hotshoe attachment cumbersome, but astro-photography enthusiasts could well be enticed by the device's interesting "ASTROTRACER" function. This helps you take clearer photos of celestial bodies by using the in-built sensors to calculate a star's movement and then employing the camera's shake reduction system to compensate. Sounds clever, but be advised: this module is only for Pentax DSLRs -- and only for very specific models at that. You'll get full functionality with the K-5 and K-r cameras, and geotagging (no ASTROTRACER) with the 645D. Oh, and you'll need to make sure yo
