RIM BlackBerry PlayBook Review by Walt Mossberg
Walt Mossberg at The Wall Street Journal:
The screen is beautiful, even though it has a lower resolution than the iPad’s. And the cameras are better than the iPad’s.
Resolution. Marketing folks sure botched this one. Here’s what it means according to Webster:
6 b : a measure of the sharpness of an image or of the fineness with which a device (as a video display, printer, or scanner) can produce or record such an image usually expressed as the total number or density of pixels in the image
In other words, the term resolution does not refer to a format like 1024×600, but instead to something like 169 pixels per inch. Resolution is a term to describe density. So. The PlayBook has a resolution of 169 ppi; the iPad 132. The PlayBook has a higher resolution than the iPad. It should instead read:
The screen is beautiful, partly due to a higher resolution than the iPad’s.
I think we all know this: just because a camera’s image sensor has more pixels does not necessarily mean it produces photographs with better quality. Though the iPad takes some crummy stills, it does a fine job of capturing 720p video out back. There’s also the experience of capturing videos. I’ve used smartphones that capture 1080p HD video, but because of lag the experience was terrible. I’d like to know if capturing video on the PlayBook is lag-free and enjoyable, like on the iPad.
