If your main motivating factor is performance, Linux is the way to go. I too run a dual boot Linux/OSX system on my 2nd notebook, and have found Pd patches running in linux to run with <b>much</b> less cpu load than OSX. If you choose to use JACK instead of Portaudio on OSX, you can reduce their cpu load significantly (fyi, JACK isn't yet compatible with 10.5). The Mac/Linux system is probably the best of both worlds + you can satisfy your OS X package needs with Darwinports (which rocks). <div><br class="webkit-block-placeholder"></div><div>As for windows, haven't used it for audio since 1999 and don't intend on going back.</div><div><br class="webkit-block-placeholder"></div><div>Do you have any other main considerations besides price and performance when looking for a new machine?</div><div><br class="webkit-block-placeholder"></div><div>~Brandon</div><div><br class="webkit-block-placeholder"></div><div><br class="webkit-block-placeholder"></div><div><div>On Dec 27, 2007, at 6:44 PM, Derek Holzer wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite">Hi Mike,<br><br>Mike McGonagle wrote:<br><blockquote type="cite">Hello all,<br></blockquote><blockquote type="cite"><br></blockquote><blockquote type="cite">I was wondering if anyone has done any sort of "Platform" comparisons?
