    Magic Mouse 2 and Magic Trackpad 2
    -------------------------------------------------
    Apple today announced that it has updated its iMac lineup, 
    introducing new 21.5-inch iMac with Retina 4K Display and 
    27-inch iMac with Retina 5K Display models.
    The all-new desktop computers feature faster processors 
    and graphics, two Thunderbolt 2 ports and up to 2TB of 
    Fusion Drive storage for stock configurations. The 4K 
    21.5-inch iMac has a 3.1GHz Core i7 Broadwell processor 
    and integrated Intel Iris Pro Graphics 6200, while the 
    5K 27-inch iMacs have 3.2GHz to 3.3GHz Core i5 and i7 
    Skylake processors and dedicated AMD Radeon R9 GPUs.
       "From the first iMac to today, the spirit of 
        iMac has never wavered ã deliver the ultimate  
        desktop experience with the latest  
        technologies, gorgeous displays and  
        cutting-edge designs," said Philip Schiller,  
        Apple's senior vice president of Worldwide  
        Marketing. "These are the most stunning iMacs  
        we've ever made. With our gorgeous new Retina  
        displays, more powerful processors and  
        graphics and all-new Magic accessories, the  
        new iMac continues to redefine the ultimate  
        desktop experience."
 
    Apple has also launched all-new Magic accessories,  
    including the Magic Keyboard, Magic Mouse 2 and Magic  
    Trackpad 2.
    The new Magic Keyboard, US$99, features Bluetooth for  
    wireless connectivity and a built-in rechargeable  
    lithium-ion battery that charges fully in about two  
    hours using a Lightning to USB cable. The redesigned  
    keyboard has a reengineered scissor mechanism with 33%  
    more key stability and a lower profile for more precise  
    and comfortable typing.
 
    The new Magic Trackpad 2, US$129, features Force Touch  
    and a larger edge-to-edge glass design with 29% more  
    surface area. The new Magic Mouse 2, US$79, also has a  
    built-in rechargeable lithium-ion battery and redesigned  
    internal structure that includes fewer moving parts. The  
    trio of new wireless accessories are available through  
    Apple and resellers today.
 
    The new 4K 21.5-inch and 5K 27-inch iMac are available  
    today through the Apple Store, Apple Online Store and  
    select authorized resellers, with pricing starting at  
    US$1,499 and US$1,799 respectively. Apple will also  
    continue selling the non-Retina 21.5-inch iMac in two  
    models starting at US$1,099 and US$1,299.
 
    The new iMacs include a Magic Keyboard and Magic Mouse 2  
    in the box.

So where's the updated *proper* keyboard with a numeric keypad.  :-(
Never mind, the existing version is better anyway thanks to not relying
on silly batteries that run out just when you need them not to and wear
out to uselessness.
