Of course this is only speculation but here are some of the things I think we might see with Leopard. 1. Resolution independent bitmaps Well not quite resolution independent but there are a few Photoshop plugins that allow you to blow up an image quite substantially, with little loss in resolution. iPhoto users should love a feature like this. 2. More XML (aka Spotlight) I'm under the impression that XML is about content management, which is what I think Spotlight is. But instead of typing in a search, you click on a special icon representing say, applications. Every application, no matter where it is on your drive instantly appears. (In order of course). 3. Live column view This isn't really a major, but when you're in column view you have to click on a folder to view it's contents. Just a mouse over should suffice. Would speed up navigation considerably. 4. Broadband connections and mobile phones. People are increasingly favouring the "mobile office". A lot of people are also switching to broadband. Basically the land line phone as we know it is on the way out. VoIP and mobile phones are taking over. I expect to see something major from the next Mac OS X in regards to this.
