Raskin complains

yes, but when you were designing computers, they didn't really have much functionality, did they? Do you really want to go back to running a single application at a time? Keep everything in ROM? I have some old macs in my basement, if you want one? Yeah, I didn't think so.

Guardian Unlimited - Raskin:Jef Raskin was one of the creators of the Mac and invented the click-and-drag interface Perhaps the longest surviving legacy of your original design is its "appliance" nature. Has this simplicity of design been key to the Mac's popularity?

Yes, but unfortunately, the Mac is now a mess. A third party manual (Pogue's The Missing Manual) is nearly 1,000 pages, and far from complete. Apple now does development by accretion, and there is only a little difference between using a Mac and a Windows machine.How do you rate today's Mac user interface?My original vision is outdated and irrelevant. The principles of putting people first, and designing from the interface to the software and hardware, are as vital today as they were then.

and blah blah frickin' blah. I'm quite happy with my mac; do I think there is nothing worth changing? No, of course not, but what Raskin seems to imply is hogwash.
