When news surfaced early this year that a Florida company called Psystar was selling computers with Apple's operating system pre-installed, many wondered when Apple is going to go after them.

Well, that day is here.

Apple has filed suit against Psystar on July 3rd saying Psystar's Open Computer infringes on its copyright, trademark, and other claims, according to News.com's Ina Fried.

On Psystar's Open Computer product page, the company asks, "Why spend $1999 to get the least expensive Apple computer with a decent video card when you can pay less than a fourth of that for an equivalent sleek and small form-factor desktop with the same hardware."

If Apple's suit is successful, the answer is because that's the only way one can legally obtain an Apple computer.
