Bing's image search is better than google's. Hands down. While this has been popularized for ...ehem...nsfw reasons, it's also very useful to find charts and visualizations related to a particular topic. As an example, I was searching for charts that showed laptop vs desktop market share, and bam! There's the latest projections.
Tangent: I wonder if Bing has an advantage in that most people perform SEO for Google; so long as Bing has different algos it may be “immune” to Google-focused seo?
