Rob Gonda: “Web 2.0 on the desktop! A new feature!” Um, no, Rob, Sorry…
It’s hard to imagine that this is actually a new thing in Windows. (…)

This can’t really be called “news”, since I clipped this PC Magazine review in late December, 2005. But a Martian never forgets! Besides, PC Magazine still brazenly displays this information on its website as if it were fact, not fiction. After reading through the info I’ve gathered in the last half hour, you be the judge of the facts in this case.

The serious error here is that PC Magazine lists the Apple Power Mac G5 Quad as costing… guess! You’ll never guess how much they say it costs. Honestly.

OK, I gotta spill the beans at some point. PC Magazine says a Quad costs $7,023 to $9,522!

That struck me as very odd, since I had just bought a new Quad for myself in December, and I didn’t pay anywhere near $7,000-$9,500 for it. The unit I bought was hardly the base model, either: I had upgraded to the $350 Nvidia GeForce 7800 graphics card when it became available and also added Bluetooth and Airport wireless cards for $99. And I got all this for only $3,448! How is this possible, you ask? Read on.

As I mentioned in an earlier post, the whole Ajax/Web 2.0 thing that’s happened this last year reminds me vividly of the mid-1990’s. Back then, the web was brand new, it was exciting, everyone was learning how to build web applications, developers were totally turned on and creative, everybody was pointing out cool new apps and sites, and the potential of this new computing platform seemed unlimited. Leading the charge was a young company that built software for every operating system under the sun, and they clearly had a solid vision of where they were headed. During 1994-96, Netscape introduced one astonishing new client-side technology after another to what a web browser could do–tables, animated graphics, client-side imagemaps, frames, cookies (yes, these really were a vital improvement to the web client), and something they called Javascript.

Each of these technologies offered dramatic new ways of presenting information in a web browser, and developers who loved new gadgets glommed on to every advance, racing each other to see who could do the coolest things with these first. A lot of mistakes were made–a lot of really ugly eggs were hatched–but excitement and optimism were the buzz feelings. With Netscape in charge, you felt like you do when working as a protege with a master hacker: Does this guy ever stop pulling amazing tricks out of his sleeve?

One of the promises of Netscape’s vision was that the web–and, in particular, the web browser–could make one’s choice of operating system irrelevant. The web could level the computing playing field, since applications built for the web were applications for all, regardless of what OS you happened to prefer. What worked for NeXT, OS/2, Irix, Solaris, and Windows would also work just fine on Linux, Mac OS, Be OS, HP-UX, and BSD. The web browser could be the OS, and the only limiting factor in what you could do would be your hardware and connection speed. Microsoft’s lock on the computer desktop could be broken, and new competitors in operating systems and computers could unleash the full potential of the personal computer to improve our lives–both at work and at leisure.

Only, it didn’t quite turn out that way.

This article inventories the Ajax/DHTML toolkits now available and grades each from A to E on the degree to which they adhere to a cross-browser ideal. The good news is that if you want to build astonishing Web 2.0 applications in 2006, you’ve got a lot of fine Javascript libraries to choose from! And nearly all of the Grade A libraries are open-source, so you can build without shelling out a license fee for the privilege. The bad news is that some of the most prominent players in the field fall far short of that mark.
