No one has actually attempted to answer the question, so I will toss out a few ideas myself....
Actually, I was about to post!
...Flame away, this is simply an honest inquiry...what the heck is Apple thinking? I honestly thought Apple was above releasing products that appear to be only half-baked in both the software and hardware.
Such as the Newton? Hand-writing recognition that didn't work on the product's release and a PDA product that didn't fit into a pocket, aren't exactly hallmarks of a marriage of perfectly designed hardware and software.
The cracks that appeared in the Cube's casing was a PR disaster - Apple had no idea they would appear and when they were discovered, the excuse was it was equivalent to grains in finely produced antique furniture.
The Powerbook 5300 had problem with the battery fires and although it had a hot (no pun intended) swappable drive, there wasn't enough room for an internal CD drive.
Those are just three examples of troubled releases off the top of my head - I feel the iPhone 4's future is going to be waaaaaaaay brighter than these products. That's just my opinion mind.
You may have more Apple stuff than me but I did manage to scrap a living for a few years as a Mac hack for a few magazines, so I think I'll need a bit more convincing about your own expertise.
Having a naive, rose-tinted view of Apple as it was, is rather sweet, but to imply that Apple's product launches have been gloriously trouble-free until iPhone 4, amusing as it is, is completely wrong. Sounds like you need to read up a bit about Apple's history - happy to suggest a few books and online resources if you like.
Totally weak comparison, today's phone issues are all over the media....almost all major and minor media, whether tech related or not, have covered at least one of apple's flubs with this new phone...in fact, name media outlet that has not covered an issue with this phone....bet you cannot.
The iPhone 4 was a bigger news story before any faults were reported than the other models.
Before it was even released, there were reams of filler material like

The situation is that is there's an iPhone 4 angle, the press will run with it.... no matter what the story is and how strong it really is.
From what I infer, you're saying the iPhone 4 problems are bigger than earlier models because they're getting more attention in the press, which is kinda sweet but shows a bit too much faith in the media.
