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 your camera's firmware is up-to-date. Peer carefully through that lens and you'll see the O-GPS1 heading for a July landing, priced at $250.
If you dig the stylish look on the Linksys E4200 802.11n router but prefer something more wallet-friendly, then Cisco's latest range of home routers and switches will likely suit your taste. Gone are the curved grooves and blinking LEDs on the top, but these routers -- ranging from $59.99 to $159.99 -- still go about their usual wireless business at up to 300Mbps, with additional simultaneous dual-band support on the pricier E2500 and E3200. Like their predecessors, you'll also find a refreshed, feature-packed Cisco Connect software suite in the box, which promises to make installation and management a whole lot easier. Also notable is the upcoming virtual USB feature that connects printers and storage devices to the network -- the E3200 and E4200 are expected to receive this update in the summer. As for the switches, you have a choice of three new models going from $29.99 for five 10/100Mbps ports, all the way up to $74.99 for eight gigabit connections. All thes
