iMac is the standard bearer when it comes to all-in-one desktop. And these new iMac models with gorgeous LED backlit displays and faster processors keep the iMac on top of the heap. Computer World’s Ken Mingis says in his iMac review, “Desktop, in some ways, have fallen out of favor, given the prevalence of wireless connections and the public’s desire for mobility. But with an absolutely stunning screen, a lot of under-the-hood performance improvements, the wireless keyboard and the new mouse, and flexibility that makes it fit in at work and at home, this new iMac could lead to a resurgence in desktop sales for Apple.”
