Without the usual fanfare, Apple updated several components in its Macintosh computer line on Tuesday September 20th. Included in this major update are the MacBook, the mini, the Mac mouse, the Apple Remote, plus a minor update to their wireless products – the Airport Extreme and Time Capsule. In this round of updates, the iMac has received some major renovations. The Apple iMac update brings some major design changes. The new iMac is still available in two sizes. The now old iMac had either a 20-inch or 24-inch LCD display. The new iMac is available with either a 21.5-inch or an impressive 27-inch LCD display. These new 16-by-9 ratio displays have a resolution of 1920 by 1080 (considered full HD) on the 21.5-inch model and 2560 by 1440 pixels on the 27-inch model. This is also the first time Apple has used LED backlight technology in an iMac. This technology has been used for a while now in Apple’s notebooks, and the 24-inch Cinema Display, introduced at the end of last year.
