Microsoft wants Bing Desktop to transcend the limits of web-based search, and that's especially clear with a newly posted app update -- it's all about doing what most browsers can't. The software brings inline searching that lets users run Bing queries on websites, PDFs and Word files just by selecting text. Newshounds also don't have to wade into every article now that there's both at-a-glance previews and a trending stories section. We suspect most users won't mind the real-time weather forecasts and live Facebook notifications, either. Existing Bing Destkop users should automatically receive the new features in the days ahead, but those who refuse to wait can grab the upgrade straight from the source.
