Navigator's Death Blow? IE 5.0 Arrives Jesse Berst, Editorial Director ZDNet AnchorDesk Will Netscape's Web browser become the Lotus 1-2-3 of the Internet era -- a pioneer that is eventually eviscerated by Microsoft? The answer will soon become apparent. You just have to know where to look. Version 5.0 of Microsoft's Internet Explorer went into widespread beta yesterday. Click for more. Version 5.0 of Netscape Communicator will be here soon. There's lots of attention on the differences between the two browsers. Earlier this year, I explained the fundamental distinction. Netscape is superior at breakthrough ideas. Microsoft is better at incremental improvements. You can see Microsoft's philosophy at work in IE 5.0. It offers improvements in search capability, a redesigned email client, better bookmarks and a superior implementation of XML. Distribution. As the Web goes mainstream, Netscape must make its browser the first one people use. Right now, when people get a new computer, they almost always begin their browsing experience with IE. And they rarely switch. Lock-in. Lock-in occurs when it becomes too painful to move from one product to another. Since both browsers are free, Netscape must convince users to "invest" in other ways. The best way is to add features that tie users to the Netcenter Web site. Smart browsing, address-book synchronization and anytime/anywhere email are three current Netcenter services with lock-in potential. Netcenter will be offering more and more services that 1) reside on Netcenter and 2) require a Netscape browser to work properly. How to predict the winner. To spot the winner, look for developments that impact distribution or lock-in. On the distribution front, watch to see if Netscape can win deals with Microsoft loyalists such as Dell Computer. Deals that make the Netscape browser the default on new computers. And Internet Explorer a hard-to-find option. On the lock-in front, watch the evolution of Netcenter. If you find yourself wanting to upgrade to Netscape's next browser because you want the services on Netcenter, then Netscape is successfully executing its lock-in plan.
