Romko,
There is some merit to a dislike of a particular architecture. Often it relates to frustrations or having paid too much for something. Think of the backlash when Apple dropped the price of the iPhone. Some beta buyers felt betrayed and used.
Another example was the Lisa. After spending ten thousand dollars, people were not happy that the Mac was cheaper and a better quality product.
Yet another comes from the Mac IIfx. People spent ten thousand dollars on it and yet Apple never finished some of the SCSI interface software because the Quadra series was coming out and it used different software. Even though the IIfx was 'wicked fast,' it cost a lot of money and Apple abandoned the upgrade path.
Next might be the Blue and White. It was designed to give the masses onboard USB and IDE hard drives standard. People wanted to be able to put cheap PC parts into a Mac. But the B&W had issues with data corruption. Then there was the early G4s, one called the Yikes.

If I remember correctly, the Yikes page used to have a little more editorializing. Something about taking a G3 board design and creating a patch so it could be used with the G4 chip until the real G4 board could be finished. Many times the marketing department wants something to sell before Christmas, even if R&D is not done with design upgrades. So they cobble together a quick fix and get something inferior on the market.

It does not do much good to be negative about everything but I had a client spend $17,000 on some Avid video editing software to use on an 8100 with 9 gig raided hard drives. Avid never did get the software to work properly for an extended period of time. After spending that much money and being promised a product that is never delivered, it is understandable that some people get upset.
Probably the biggest consumer protection law suit was against Iomega. Thirty five state attorneys general sued the company because of what was called the "click of death." Tens of thousands of people lost data to defective Iomega zip drives that killed data on zip disks. I have had many quality products from Iomega but I will never forget the click of death because I also lost data. The company was forced to own up to their mistake. Unfortunately, instead of recalling the defective products, all they did was offer a coupon for a small discount on a new zip drive. No Thanks.
You asked for why some people rant? There is why.
