Apple iMac MK142LL/A All-in-One: iMac features a gorgeous 21.5" widescreen display, powerful Intel processors, superfast graphics, and more. All in a stunningly thin enclosure that's only 5mm at its edge.
I'm a Windows engineer at work, spending all my days fixing problems. When I get home, I just turn the iMac on and use it. Period. It's intuitive, easy, fast, and I don't worry about hot fixes, patches, or security vulnerabilities.
