Good article, but the BlackBerry of choice right now is the 9700. The camera on it is bloody good. With a little care you can take a photo of an A4 page in 12- or 14-point type and it's basically legible once you've emailed it to someone... I just mention this apropos of nothing.
Last I tried, with a Curve, it was flaky and basically impossible to get working on a mac. But it seems to vary significantly with the OS version and model of blackberry.
