Top Tech Blunders: 10 Products that Massively Failed
Rambus RDRAM

Before Rambus RDRAM ever appeared on PCs, it was a component of the Nintendo 64, which utilized 4MB of RDRAM running at 500MHz. Two years later, PC builders would get a taste of this proprietary RAM when Rambus and Intel entered into a license contract to exclusively use RDRAM with Intel CPU chipsets. That meant that if you wanted to build a Pentium 4 system with an Intel motherboard, you had to use RDRAM. Intel even planned to make a half billion dollar investment into Micron fabs to boost the adoption of RDRAM. Intel figured that the success of RDRAM could generate a lot of licensing revenue from Rambus, and was confident in the superiority of RDRAM over alternatives. At the time, PC-133 and even DDR SDRAM wasn't nearly as fast as the 400MHz (PC800) Rambus offering, and it wasn't until dual-channel DDR 400 came out that SDRAM was dethroned.
How it Failed
Even with its speed advantage, memory vendors strongly resisted the adoption of RDRAM due to the high cost of manufacturing and expensive licensing fees. And as SDRAM prices continued to fall, motherboard manufacturers opted to utilize chipsets that supported SDRAM from chipset makers like VIA rather than Intel. Even Intel's subsidy of RDRAM by bundling RIMMS with Pentium 4 CPUs didn't help the standard. Today, Rambus has ceased development of RDRAM and is currently pursuing lawsuits against other RAM makers which it alleges conspired to depress the price of DDR memory to [successfully] kill off RDRAM.

3Com Audrey

The first "internet appliance" the 3Com Audrey was poised to revolutionize the way we interacted with computers in the household. Released in 2000 for a modest $500, this touchscreen PC was marketed as a way for families to take the PC out of the office and into the family living space. It came bundled with a dial-up modem, two USB ports, and a Compactflash slot, meaning you could email, or surf the internet for dinner recipes without leaving the kitchen. It even synced up to Palm handhelds (though those didn't fare so well in the long run, either). The Audrey's creators envisioned the device as the hub of the connected household.
How it Failed
Even though the Audrey attracted lots of media buzz and a devoted following, not enough consumers were convinced that they needed a simplified computing device for their living rooms or kitchens. The dot-com crash didn't help matters, and 3Com pulled the plug on the Audrey just a few months after its launch. The open-source community quickly adopted the device to hack its operating system, and has since developed custom internet browsers, MP3 players, and photo viewing software for the Audrey.
Despite the Audrey's failure, the concept was sound, and it paved the way for current all-in-one PCs like HP's Touchsmart line and Dell's Studio One computers. In fact, one of our current favorite gadgets, the Chumby, has a striking resemblance to the Audrey.
Intel Netburst
Intel’s NetBurst. Like all things, Intel’s NetBurst architecture that was used in the Pentium 4 can be spun two ways: a success that sold tens of millions if not hundreds of millions of parts over the years. From the enthusiast point of view though, it was a failure. During its life, it was lost various battles to the Pentium III it was supposed to replace, AMD’s Athlon and Athlon XP as well as the Athlon 64.
How it Failed
As we’ve said before, the Pentium 4 could never close the deal and coffee, as we know, is for closers. That’s not to say there weren’t successes. The Extreme Edition variants were indeed fast as were the initial “Northwood” derivatives. Near the end of its life, the Cedar Mill versions also had good reps as overclocking parts. Still, for a company that had a multi-decade track record of smoking the competition, the Pentium 4 / NetBurst era is nothing to call a success. It didn’t help that the first Pentium 4s were tied to the uber-expensive Direct RDRAM memory that ignited a rebellion among RAM vendors against Intel (see above).
The Pentium 4 even faced an internal rebellion. With the realization that the hotter than hell design would never make it a true mobile CPU, a splinter development started working on a Pentium III derivative codenamed Banias. Banias would eventually turn into Pentium M which morphed into Core Duo and finally Core 2. More than AMD, Core 2 put the final bullets into the Pentium 4 and sent it to languish in the stomach of the Sarlacc for a thousand years.
