Will AJAX Threaten Windows Desktop?
prostoalex writes "They are not your father's HTML pages anymore. AJAX interfaces are getting more complex and versatile, relieving the user of the necessity to reload the page, and thus are becoming more like your average desktop apps. The catch? AJAX apps work in any browser out there, making the OS layer a bit irrelevant. Will the trend threaten Microsoft desktop near-monopoly? Or are we hearing the story of poorly debugged device drivers again?"
The web applications that benefit from AJAX benefit because the experience is snappier, and because it can behave a little more like a desktop application. That's all.
Making web applications look, feel and work like desktop applications take time and require hard work, and it's mostly useless because the tasks that wouldn't be hurt by being transferred from a desktop application to a web application are few. Programs like The GIMP and Photoshop are near impossible to do as web applications, and that's not because HTML wasn't build for web applications, but because they shouldn't be web applications in the first place.
Wow, you guys must be really enjoying your high out there. Sure, AJAX is nice, but it's not going to replace desktop apps anytime soon. Note that Flash and Java applets have been available for a long time, and they are actually more flexible than AJAX. Also note that AJAX, contrary to what you may think, does NOT work in all browsers. In many browsers, your experience will still be limited to some text on some page, at best. And people actually _do_ use these browsers.
As for the people who think that Microsoft is going to get into losses because of this, you should _really_ cut down on your dope. In case you had forgotten, Microsoft has not traditionally been defeated by superior products, and they are actually working on a system of their own for providing a rich user experience through the web (XAML).
As long as web standards insist on the heavyweight request-response model, they will never achieve the snappiness, responsiveness, and flexibility that can be achieved with proper applications.
Here's some food for thought: imagine a simple instant messaging program, written in your favorite programming languages. One the connection to your chat party is established, all you need to do is send the text the user types, and wait for incoming text and display it. Now, imagine implementing the same sort of application in an environment where the only possible communication is you making an HTTP request and receiving an XML response.
Please correct me if I got my facts wrong.
AJAX is also good for intranet applications that need to access the companys database for example.
It much easier to upgrade an AJAX application than a traditional application for 2000 employee computers.
The IT staff probably loves this trend!
It's not Photoshop or heavy-media type applications you should be thinking of, it's the simple end-user-interacts-with-database type applications - where you don't need to have lightning-fast feedback. It's the sort of applications that can work fairly well even as "traditional" web applications - eg. webmail, usenet, flickr, etc.
Using AJAX-like techniques just opens the gate a bit further and makes it possible for quite a few more types of applications to exist and run on the "web" platform.
And the thing is that lots of non-computer-geek people really like web applications - they tend to be simpler and easier to use, there are no download/install issues, you can in theory access them from any computer with a network connection and a web browser (ie. just about anywhere), you don't have to worry about managing or backing up your data because it's being looked after by professionals (for what that's worth *grin*)...
No, webapps in general (and AJAX-type web apps specifically) can't do everything. But they can do a hell of a lot more than you might think.
