Google has been putting quite a bit of its weight behind its Chromebook initiative, but it’s been rather quiet about how well these browser-centric laptops have been selling. Judging from the latest data from online advertising firm Chitika, Chromebooks remain a novelty. Across Chitika’s network, just 0.019% of all traffic comes from ChromeOS. To put this into perspective, Sony’s PlayStation, which isn’t exactly a web browsing powerhouse, easily beats ChromeOS with a usage share of 0.042%.

This data, Chitika told us, includes all ChromeOS traffic from all ChromeOS versions currently in use (given that ChromeOS updates itself, we can safely assume that most users are currently using the most recent version, though). As usual, it’s worth remembering that this data only includes sites that use Chitika’s advertising service. The data was compiled between June 7 and June 13 and aggregates data from “hundreds of million impressions.”

As I noted in my Samsung Series 5 Chromebook review last week, the actual devices have greatly improved since the first generation. They do remain niche products, though, and don’t appeal to a mainstream audience (yet).

Earlier this week, Chitika’s also took a look at the tablet space. Here, unsurprisingly, the iPad dominates and is responsible for 91% of all web traffic to sites in Chitika’s network. What was somewhat surprising about this data, though, was that the Barnes & Noble Nook overtook the Kindle Fire in these stats, though the difference here is between two tablets that account for 0.85% and 0.71% of all traffic.
