51% of iPad buyers own Windows PCsApril 16, 2010: 2:51 PM ET
Also, 63% own Macs, 8.5% iPhones, 2.89% Linux boxes and 1.3% Android phones
Dan Ruby at Chitika Labs -- the folks who run the much revised live iPad tracker (907,000 as of Friday afternoon) -- sent along the bar chart at right.
It shows, based on a survey of nearly 75,000 early iPad adopters, some of the non-Apple (AAPL) devices they own.
"That's a big part of what I love about Apple's non-Mac products," Ruby writes. "They tend to bridge that Apple-Microsoft divide in users."
