        <p>Apple is bringin' it back&mdash;"Back to the Mac"&mdash;at this week's <a href="http://arstechnica.com/apple/news/2010/10/apple-announces-back-to-the-mac-event-for-october-20.ars">Mac OS X preview event</a>. There has been plenty of speculation about what Apple plans to show off&mdash;aside from a first look at the next major version of Mac OS X, that is. Will it be new notebooks? The next-gen iPad? A for-really-real, I-can-actually-buy-this white iPhone 4? The mythical Xmac mini-tower? A new UI borrowed from iOS?</p>
        
        <p>We here in the Ars Orbiting HQ have our own list of ideas that we kicked around the water cooler recently&mdash;some probable, some hopeful, and some just beyond left field.&nbsp;</p>  <h3>That sounds nice</h3>
        
        <p>Science Editor John Timmer would like to see "a conduit system like Palm's," which would let any application sync arbitrary data with an iOS app. Actually, Apple has a similar system, called iSync, but it's never been used directly for this purpose. Apple routes everything through iTunes, and typically limits dat synchronization between its own apps.</p>
        
        <p>A standardized API to allow developers of a desktop app sync data with an iOS app&mdash;or vice versa&mdash;would be welcome by both users and developers.</p>
    </div>
    
    <div id="center"><p>Project Manager Clint Ecker would like better synchronization as well&mdash;between two or more Macs. He envisions a sort of Dropbox-style syncing of home folders, with versioning, so every machine has the latest copy of important files and can access older versions as necessary. It would be sort of like "MobileMe syncing mixed with Time Machine."</p>
        
        <p>Ecker also would like to see Apple do more to abstract away the filesystem Ă  la iOS for most tasks. "Apple should make it possible to not have to think about any of that stuff and just work on creating/consuming,"...
