Unmanaged high customer acquisition costs can quickly lead to financial instability and failure.

Tablets (and similar devices) require core standalone functionality for essential tasks and a robust app ecosystem; unnecessary dependencies deter users.

Products need unique differentiation and should solve new or existing problems better than current solutions to justify their existence. Don't just chase market leaders without innovation.

Products must solve real problems for consumers and offer clear value, not just showcase technology.

Overly restrictive and consumer-unfriendly DRM implementations can be counterproductive, failing to prevent piracy while simultaneously fostering strong negative sentiment among legitimate users, leading to brand damage and product underperformance.

Product quality is paramount; defective products lead to failure and negative public relations.

Core product features must work flawlessly, especially if they are the primary selling point. A product must offer a clear advantage over simpler, cheaper alternatives.

An overly complex and expensive product that offers no significant advantage over simpler, cheaper alternatives (or even manual effort) will fail. Focus on genuine value and user benefit rather than unnecessary engineering.

Product performance must be balanced; excessive power or strength can be detrimental to the user's property.

Products and services must offer competitive advantages and user convenience, especially when facing disruptive innovations. Avoid unnecessary complexity and proprietary systems that limit user choice.

Consider the social acceptability and perceived necessity of a product; some innovations don't exist for good reasons.

Even genuinely improved products need effective communication of their benefits to justify price and gain adoption from the target market.
