Well, this "article" is so bad, I'm not sure were to start.
1) It basically states that Java has failed, yet we see PDA/phone manufacturers lining up to support it, and developers seeing it as a blessing for portable and easy development, specially on embedded devices. Also "I’ve seen some Java apps that rock and some that are bloated memory sucking productivity killers" seems to be a rather generic phrase, were one can replace the "Java" word by just about any platform out there and it will still hold true...
2) The 3 environments are presented as if they were the same thing under a different name. They have the same concept, yes - it's called competition. But each surely have pros and cons against each other (which are not presented in the article)
3) The last paragraph is so ridiculous it doesn't deserve any comment.
In the end, this "article" is obviously written with the sole purpose of attacking Amiga Inc. and there is no evident research behind it.
Still, in my opinion, it is true that the intent platform has a great potential that is being misused by Amiga and Tao themselves and the original idea of replacing the classic OS by the DE still would be the way to go if the platform is to attract the average "Joe" into the platform, but that's probably not the plan anymore.
