Apple's new iMac
By Tony Chan our gadget man
The latest generation of iMac desktops from Apple is bigger, faster and does more tricks than ever before.
Launched this week in the United States, two new iMacs now come with either a 21.5-inch or a 27-inch display.
Image resolution starts from the basic high definition of 1,920 x 1,080 pixels for the smaller version, to a whopping 2,560 x 1,440 pixels for the larger model.
The displays are also LED-backlit, which turns on faster and is brighter than standard displays.
Besides being bigger, the new products are also faster.
The 21.5-inch model now comes with an Intel Core 2 duo processor running up to 3.33GHz.
The 27-inch model is equipped with a quad-core processor from Intel running at either 2.66GHz or 2.8GHz.
While the clock speed is lower for the quad-core models, having twice the number of processor cores means it does everything twice as fast as dual-core chips. But the coolest thing about the new iMac has to be the new mouse, called the Magic Mouse by Apple. Instead of a click and scroll control, the Magic Mouse is basically a touch pad, like those on notebooks.
You tap the surface with your finger to click, or slide your finger up, down or sideways to scroll through webpages and documents.
The iMacs cost US$1,199 and US$1,699 in the US. No release date has been set for Hong Kong
Pros: bigger displays with ultra-high definition resolution, faster processor, new touch- and gesture-based mouse
Cons: have to learn a whole new way to use the mouse
