The two most impressive operating systems were the two with the briefest histories: iPhone OS and Android.

Both are built for Internet-centric devices, both are not only functional but fun, and both make extending your phone's capabilities with new applications extremely easy. At the moment, iPhone OSbeats the newer, rougher

Google OS; over time, Android's open-source design and lack of restrictions on third-party developers could give it an edge over Apple's more locked-down approach.

Among the old-timers, the BlackBerry OS is doing a solid job of preserving the strengths that made it popular in the first place while keeping up with the times. In contrast, I regret to report, Windows Mobile and S60 3rd Edition

are aging badly.
