Those using Apple's boot camp are in for a bit of a surprise, as Apple may start charging for use of it once Leopard is released. It's no secret that it will be a part of Leopard upon release, and existing Mac OS X Tiger users may end up needing to pay a $29 fee in order to get the final version. Currently, the beta is still free, though Apple has stated that they will not support Windows on the beta once the final version is out.
The beta has been very popular among enthusiasts, as well as people wanting to experiment with both OS X and Windows on the same machine. No official statement from Apple regarding a fee has come out, though we've already seen them do it in other areas, such as their plan to charge to enabling latency 802.11n functionality in MacBook pros.
