The Webtop
Software that was once the bailiwick of desktop computing is now going online. In fact, these web-based applications may someday entirely replace your desktop suite.
By Erick Schonfeld, Om Malik, and Michael V. Copeland

SAN FRANCISCO (Business 2.0 Magazine) - It's been a long time -- all the way back to the dawn of desktop computing in the early 1980s -- since software coders have had as much fun as they're having right now. But today, browser-based applications are where the action is. A killer app no longer requires hundreds of drones slaving away on millions of lines of code. Three or four engineers and a steady supply of Red Bull is all it takes to rapidly turn a midnight brainstorm into a website so hot it melts the servers.

What has changed is the way today's Web-based apps can run almost as seamlessly as programs used on the desktop, with embedded audio, video, and drag-and-drop ease of use. Behind this Web-desktop fusion are technologies like Ajax (asynchronous JavaScript and XML), Macromedia's Flash, and Ruby on Rails. We'll spare you the technical details; suffice it to say that these technologies are giving rise to a new webtop that may one day replace your suite of desktop applications.

Start with Writely, a free online word processor that anyone who knows how to use Microsoft Word will figure out in a few clicks. Then add Zimbra, which is taking a swipe at Microsoft Outlook with an online e-mail application that has all the latest Ajax tricks built in. Glide a mouse over a message that includes a date, and your calendar for that day pops up. Move it over a website address, and an image of the page appears.

For an online spreadsheet, try Tracker, the latest release from JotSpot (better known for its group-editing "wiki" software). Tracker becomes an interactive website open to viewing or changing by the people you invite. Users also will soon be able to subscribe to a particular spreadsheet row (say, "Sales in China") via an RSS feed.

All of these programs link to myriad open APIs--advanced program interfaces that serve as building blocks for new applications--and data on the Web from Amazon (Research), Google (Research), and others. Thus can the information on your desktop be fused with the entire Web through a powerful and increasingly invisible bridge between the two.

Google, Microsoft (Research), and Yahoo (Research) are energetically trying to crash this party. Microsoft recently launched Windows Live, a personal online command center for e-mail, RSS feeds, and other content, and is preparing to follow up soon with Office Live, a website-hosting and online project-management service that taps into the existing Office desktop programs.
