3-G wouldn't be here, anywhere. Both major 3G systems, CDMA-2000 (Qualcom) and W-CDMA (GSM successor) are based on CDMA. And when Sprint rolled out IS-95 CDMA, many people did not believe it would work. No freedom to use a new techology (as in the Europe) means slower technological advancement.
Of course, there is the downside of incompatibility. But, consider the PC world -- standardization on Windows has had its benefits (large customer base for ISV's and hardware manufacturers) and disadvantages (PC's really have not changed much, and are still user-unfriendly and unreliable). At least you legally can run Mac OS, Linux, BSD, Solaris, OS/2, etc.
