Crippleware has been defined in realms of both software and hardware. In software, crippleware means that "vital features of the program such as printing or the ability to save files are disabled until the user purchases a registration key". While crippleware allows consumers to see the software before they buy, they are unable to test its complete functionality because of the disabled functions. Hardware crippleware is "a hardware device that has not been designed to its full capability". The functionality of the hardware device is limited to encourage consumers to pay for a more expensive upgraded version. Usually the hardware device considered to be crippleware can be upgraded to better or its full potential by way of a trivial change, such as removing a jumper. The manufacturer would most likely release the crippleware as a low-end or economy version of their product."〔(【引用サイトリンク】title=What is crippleware? - A Word Definition From the Webopedia Computer Dictionary )〕 ==Computer software== Deliberately limited programs are usually freeware versions of computer programs that lack the most advanced (or even crucial) features of the original program. Limited versions are made available in order to increase the popularity of the full program (by making it more desirable) without giving it away free. Examples include a word processor that cannot save or print and screencasting programs that apply a watermark logo or domain name onto the video screen such as Bandicam, Hypercam, VideoSpirit (by VeryTools) and BSR (by bsrsoft). However, crippleware programs can also differentiate between tiers of paying software customers. The term "crippleware" is sometimes used to describe software products whose functions have been limited (or "crippled") with the sole purpose of encouraging or requiring the user to pay for those functions (either by paying a one-time fee or an ongoing subscription fee).〔 The less derogatory term, from a shareware software producer's perspective, is ''feature-limited''. Feature-limited is merely one mechanism for marketing shareware as a damaged good; others are time-limited, usage-limited, capacity-limited, nagware and output-limited. From the producer's standpoint, feature-limited allows customers to try software with no commitment instead of relying on questionable or possibly staged reviews. Try-before-you-buy applications are very prevalent for mobile devices, with the additional damaged good of ad-displays as well as all of the other forms of damaged-good applications. From an Open Source software providers perspective, there is the model of open core which includes a feature-limited version of the product and an open core version. The feature-limited version can be used widely; this approach is used by products like MySQL and Eucalyptus. Several types of deliberately limited programs exist. The vendor includes a clause that features time limits to mar functionality. For example, the freeware version of Fraps has in-game video recording time restricted to 30 seconds, and with a Fraps logo on the video.〔(【引用サイトリンク】 url=http://www.fraps.com/buy.php )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Crippleware」の詳細全文を読む スポンサード リンク
