As you’re probably aware by now, Apple has no intention of releasing a 10 inch netbook with a physical keyboard and a full version of OS X. Instead the company is focusing its mobile efforts on the iPad tablet and its iPhone/iPod touch ecosystem. But as you may also know, you can unofficially install OS X on almost any computer with an x86 processor, including virtually every 10 inch netbook that’s been released in the last few years.
The site is already choc full of information on how to install OS X on netbooks using a variety of methods for a variety of different netbook models. There’s also a handy compatibility chart that should help you decide whether your netbook is fully OS X compatible or not — or help you decide what netbook model to purchase.
Bear in mind, installing OS X on non-Apple hardware does violate the company’s EULA. And downloading hacked copies of OS X without paying is illegal. But you can probably feel a little better about yourself if you pay for a fully licensed copy of OS X before beginning your experiments.
