How are their systems closed? How is theirs any different from any other company? Intel Chipsets, NVIDIA Graphics? Not a lot different than an HP or DELL. OSX? Not really...no different than Windows. I guess you could argue Linux is...but we all know how Linux has done over the years; better, but still not the desktop killer it was made out to be...
iPhone? Not a lot different than Nokia, or Motorola. They have their own hardware, as does Blackberry. iPhone OS? What about BlackBerry/RIM?
Don't confuse Open to be EVERYTHING. Open, in this argument, refers to the Internet. Standards based, such HTML, CSS, etc. vs. Flash, or other proprietary plugins etc. Every company has their own "Secret Sauce" to make them competitive, and allow them to make money...
Funny; 10 years ago people said they couldn't wait until Apple made it big, and when they did it was going change computing, etc. Now they have, and the same one's are bitching that they'r too big and need to be taken down a notch. Can't have both...not after they get $$$...once a shark tastes blood, it's over.
