It appears that there are now more iPads surfing the web than Linux-based machines.



From TUAW:

The chart above features stats from Statcounter and are based on visitor statistics averaged from over 3 million websites. As you can see the top operating systems in the US for the first 19 days of April are Windows with 82 percent of the market, Mac OS X with 19 percent of the market, then iOS with 1.18 percent of the market, followed by Linux with 0.71 percent of the market.
