Adobe Flex Rules, Everything Else Drools

This blog goes on and on about the good things about Flex, while giving only cursory coverage of Flex drawbacks

A reader feedback in response to Yakov Fain's recent article "Rich Internet Applications - State of the Union" reads as follows:

"This blog is certainly not an unbiased analysis, even though it's pretending to be just that.

The article is basically "Flex rules, everything else drools".

It goes on and on about the good things about Flex, while giving only cursory coverage of Flex drawbacks. Meanwhile, it's just the opposite regarding the other technologies, going on and on about drawbacks, and giving only cursory coverage of advantages.

Case in point, Yakov says that Java Swing development is "hugely expensive". Nonsense. First, NetBeans is completely free, and NetBeans has the wonderful Matisse GUI designer, making the development of great looking Swing UIs a snap. Second, there is JavaFX, which is an XML based declarative scripting language that is used to quickly build rich Swing UIs super easy, and is very similar to MXML/Action Script, as is featured in Yakov's beloved Flex. Third, there is a plethora of third party libraries and controls in the Swing ecosystem, that further extends Swing capabilities, and makes Swing development easier.

Then, Yakov fails to mention how expensive Flex Builder is (which, to be honest, you'll need to be truly productive with Flex), to the tune of $249 (as opposed to Free for NetBeans).

Then Yakov goes on to say one of the drawbacks of Ajax is that it involves JavaScript. Wait a minute - JavaScript is based on EcmaScript, which Flex/Flash's Action is also based on. So Yakov, why does that syntax suck for one technology (Ajax), but it's great for another technology (Flex/ActionScript). C'mon.

Yakov also completely fails to mention how much of a CPU hog Flash can be, especially on older/budget machines (which, let's face it, are quite common in the business world). So if you do a RIA with Flex, which is running in the Flash VM, you're going to get a lot of end users (corporate workers) complaining.

Flex is quite good, and has it's advantages and disadvantages. Same with the other technologies mentioned in this article.

But Yakov's article is completely biased in favor of Flex. That's fine, as Yakov has long been singing Flex praises. But he's presenting this article as a fair analysis, when it's anything but.

Thus, anyone reading this article should take it with a grain of salt."
