And what is their share now? 20-25%? That hardly indicates the majority of users don't care about specs (which also don't necessarily translate to a better device). But until about 6 months ago or so, the IPhone wasn't really behind spec-wise which weakens the argument further still. Buying an IPhone certainly doesn't imply the user doesn't care about or is ignorant to the specs, no different than buying a mid-tier PC means I don't care or know about specs.
If specs didn't matter, they wouldn't waste the print on specs or distract from the message - marketing 101 if it's not a selling point it doesn't belong in sales displays or advertisements. Consumers DO pay attention to specs - it's everywhere on just about any electronics we purchase. Several hundred bucks is not a trivial expenditure for most, and if they don't care about specs they usually get advice from someone tech savvy WHO DOES care about specs.
