Context:``` <response>: The interface of Windows 8 don cause mixed reactions. Bright talk say the system of hot corners and edge swiping "no dey very obvious" because dem no give instructions on top the functions wey dey the user interface, even the video tutorial wey dem add for the RTM release (wey only tell users to point for corners of the screen or swipe from the sides). Despite this "stumbling block", Bright talk say Windows 8 interface dey work well for some places, but e dey feel incoherent when you dey switch between the "Metro" and desktop environments, sometimes through inconsistent means. Tom Warren of The Verge talk say the new interface dey "as stunning as e dey surprising", and e dey contribute to an "incredibly personal" experience once the user don customize am, but e get steep learning curve, and e dey awkward to use with keyboard and mouse. E talk say even though Microsoft dey force all users to use the new touch-oriented interface, e dey risky, but e dey necessary to push development of apps for the Windows Store. Others, like Adrian Kingsley-Hughes from ZDNet, consider the interface to be "clumsy and impractical" because of its inconsistent design (dem even talk say e be like "two operating systems unceremoniously bolted together"), and dem conclude say "Windows 8 no be born out of need or demand; e be born out of Microsoft's desire to exert its will on top the PC industry and decide to shape am in a direction—touch and tablets -- wey go allow dem compete against, and remain relevant in the face of Apple's iPad."
