6. iPhone OS/Symbian/Android
The desktop OS that ends up replacing Windows may not be a desktop OS at all. Perhaps today's hottest client OS arena is the mobile device space. Google is preparing to release its Linux- and Java-based mobile operating system, Android, and Nokia has recently announced plans to turn its Symbian mobile OS into an open-source project. Meanwhile, Apple's iPhone and iPod Touch devices have made available to mobile application developers the most compelling hardware/software platform combination I've tested. The trick for these devices will be figuring out how best to dock with full-size displays and input devices when it's time to do more than read a document or fire off a quick message.
