In the keynote video, which I got to watch tonight, Jobs promises that there’s “top secret” stuff in Leopard which they don’t want to reveal too soon. When we’ll start to see these, I don’t know. Leopard is due in May 2007, and if Vista appears before then, I expect Apple will show its trumps to the media soon after. But they’d better be good. Improvements to Spotlight are in the works, and with Google Desktop and Beagle around, they need to be. Nautilus on GNOME is already a far more capable file-manager than the anemic Finder, and it’ll be more so by May. If we don’t see serious improvements in MacOS’s usability in Leopard, top-flight Linux distributions like Ubuntu will probably eclipse MacOS as the most useable desktop OS by the time 10.6 comes around. That’s a healthy thing: free and open-source is the future of software, and a usability victory over OSX would be a great achievement. I’m thinking of switching. Apple, you’d better make Leopard a revolution, because it could be your last chance to keep me on the platform, and I won’t be the only one to go if you don’t…
