    Jeff Yurek of Dot Color spent some time exploring the color performance of the new iPad. He, like many others, noticed that the colors on the iPad were richer than the iPad 2 and hypothesized that Apple improved the color filters. After analyzing various spectrum charts, he concludes that Apple limits the light leakage of the display by improving the color filters. You can see the improvement in an example photo on his website. The side-by-side shot shows a greenish hue leaking through the blue on the iPad 2, and the rich blue of the iPad third generation. Though pleasing to the eye, he notes that these color filter improvements require 20 to 30 percent more power to maintain the display's brightness. This may partly explain why Apple opted to go with a large, 42.5-watt-hour battery in the new iPad.

    Fisker has seen its fair share of delays on its Karma EV in the past, and now ''fewer than 50" of the vehicles -- which if you'll recall, cost over $100K -- are at risk for battery malfunction. According to Bloomberg Businessweek, A123 (the company which supplies the car's power pack) has issued a memo to customers and stakeholders, noting that "in rare circumstances" the car's batts could short-circuit due to coolant leakage from "misaligned hose clamps." A123 further explained that's already begun repairing the Karma's in question, and doesn't expect to experience to strain its relationship with Fisker due to the problem. Notably, Bloomberg also reports that 25 of the automobiles get assembled daily, with about 225 currently en-route to showroom floors -- a far cry from the company's earlier estimates for the 2011 production year. You'll find A123's full PDF memo at the source link below.
