That's quite premature -- not to mention a bit fatalistic -- but you don't get to become a multi-billion dollar, multinational company without making a few mistakes. For every Walkman and Playstation 2 there exists a handful of other Sony ideas that didn't ring true with consumers.
Some were critical flops. Some had disappointing sales. Some weren't even physical products. But, in the end, all of them fell short in one way or another. Here's hoping the Vita avoids the fate of these Sony misfires.
PSP Go

It turned out that the digital games were no cheaper than physical copies — and worse, Sony struggled getting digital copies out in time with the physical retail release. A steep price point ($250?!) gave it a black eye, while the lack of a UMD drive meant that gamers who had built inventories of PSP games weren't able to port them over without buying new copies. Though it's still being produced in North America, it was discontinued in other regions a mere two years after its release. Talk about going nowhere fast.
BetaMax

Instead, consumers rejected the company's attempt to dictate an industry standard and opted to go with JVC's VHS format, which traded picture quality for recording length (three hours to Betamax's one). The studios backed VHS as well, which would go on to rule the decade, while Sony's format would quietly fade away.
The PS3's launch price

He hadn't. That stratospheric price point put a damper on enthusiasm for the console and led a lot of fans to the less expensive Xbox 360 for their high definition gaming options. While the PS3 hardly flopped, the initial pricing is often pointed to as the reason the system isn't leading the pack like its predecessor.
eVilla Network Entertainment Center

It didn't catch on. Why? Lots of reasons, including a crummy sound system, Sony's refusal to support platforms such as Shockwave and Windows Media, and a baffling $500 price point (in addition to monthly charges). Sony recognized the problem quickly, killing the eVilla within two months and refunding everyone who bought one.
MiniDisc

They also didn't count on the advent of the MP3 file format. The adoption of MP3 as an industry standard further doomed the MiniDisc and its ATRAC format, and while it was something of a hit in Japan, it just never caught on in North America.
AIBO

Launched in 1999, AIBO (short for Artificial Intelligence roBOt) was able to walk and "see" its environment, and even recognize certain spoken commands. But outlandish pricing -- a base model cost a cringeworthy $2000 -- the digital doggie was never adopted by the mainstream market. It made it through three generations, but was mercifully put to sleep in 2006.
PSX/PlayTV

The PSX (for the PS2) and Play TV (for the PS3) had a similar function: letting people record their favorite shows using their PlayStations. Priced exorbitantly, neither struck a chord with users, and Sony killed both products before they ever set foot onto U.S. shelves.
PlayStation Home

The problem? It was boring and sprawling and players largely ignored it. Undaunted, Sony's still trying to keep Home relevant, and to be fair, it has actually gotten a lot better since its rough beginning. But most PS3 owners still bypass it and head straight into their games.
Mylo

Adding to the problems? It only worked in WiFi hotspots and originally cost nearly $300. Even worse, it was released in 2006, a mere year before Apple would change the mobile experience forever with the iPhone. The fact that Sony kept it alive for four years is the really amazing part, though.
Lair

Once hoped to be a system-seller, Lair turned out to be anything but. GameTrailers, Games Radar and countless other sites dubbed it one of the most disappointing games of the decade. And Sony didn't earn a lot of love by sending critics a reviewer's guide and a note encouraging them to "open your mind and hands for something very different" long after reviews were posted. LINK
