Nerds and Macs
Firstly: if you introduce a beta that is largely interesting to nerds, releasing it only for Windows is a mistake. I know I subscribe to a preponderance of blogs by Mac or Linux users, but even I was surprised by the number of Chrome reviews that mentioned having to run it in a virtual machine, or on the old discarded Windows box in the corner.
Not to mention the number of people who didn’t bother at all, yours truly included.
