“Our flat lens opens up a new type of technology,” says principal investigator Federico Capasso. “We’re presenting a new way of making lenses. Instead of creating phase delays as light propagates through the thickness of the material, you can create an instantaneous phase shift right at the surface of the lens. It’s extremely exciting.”

The N9 looks great, despite not having a keyboard, but it seems that it will not have as many packages and developer interest as the N900. The iPhone is not an option as a matter of principle. I've never used Android before, and am a bit bewildered by the number of choices. Is there any particular phone the Slashdot crowd would recommend as a worthy replacement for the N900 both in functionality and spirit? Or should I wait for Tizen phones to appear?

The library has about 5000 books and will be run mostly by student workers. The requirements are low cost, ease of use and maintenance, and support for Arabic and English. Barcode printing and scanning capabilities would be great as well. I've looked briefly at koha, but is there anything else out there (both hardware and software) slashdotters can recommend?"
