This updated handheld single page scanner from Pentax has a few features that could come in handy. The new DSMobile bumps the dpi up to 600 from the prior model’s 300 dpi resolution and only weighs 12 ounces. Even better: there’s no extra power components to carry along since the Pentax uses a USB cable to get power from your notebook.
Currently, the DSMobile is only supported on Windows machines, but DigitalTrends indicates a TWAIN driver is forthcoming for Max OS X soon. Watch for the handy scanner next month for around $135 so you too can scan business cards, 8.5-inch by 14-inch docs or any page size in between.
