Apple's second-generation iPad Air may get a memory upgrade, bumping it
up to 2 GB of RAM instead of the 1 GB in the current-generation device,
reports Taiwan's TechNews. According to the site, the increased RAM will be
limited to the iPad Air, as the second-generation Retina iPad mini is
expected to continue to offer 1 GB of RAM.
iPad Air 2的RAM會增到2GB。但是iPad mini Retina 2不會
Previous generations of the iPad have likely not seen a memory increase
in order to keep costs low, save space, and preserve battery, but with
some of the upcoming iOS 8 features, more RAM might be a necessity for
smooth performance.
前幾代的iPad蘋果為了省錢省空間省耗電，死都不增加記憶體。但是為了iOS 8的
新功能，蘋果必須要增加更多的RAM好讓iPad的表現順
Apple is rumored to be working on split-screen multitasking for the
iPad Air, a feature that will certainly be more memory intensive than
running a single app at a time. The feature is said to allow two apps
to run side-by-side on the iPad in multiple sizes, including 1/4, 1/2,
or 3/4. While split-screen multitasking is likely to be available on
existing devices, it may run better on Apple's upcoming iPad Air, which
is also expected to gain a new A8 processor.
蘋果正在iPad上做win 8的分屏多工功能。這個功能需要更多的記憶體。
這個功能可以讓兩個app分別在螢幕兩側執行。跟windows 8.1一樣，你可以
調整個別視窗至1/2、1/4或3/4的大小。這個新功能雖然有可能再現有的蘋果
產品上執行，但它可能在新的配有A8處理器的iPad Air上跑的比較順。
Thus far, rumors have suggested that split-screen multitasking will be
limited to the iPad Air, though support may come to the iPhone and the
Retina iPad mini at a later date. Split-screen multitasking is unlikely
to be ready for iOS 8's fall debut, but it may come as part of an 8.1 update.
目前分屏多工可能只限於iPad Air。雖然之後有可能支援iPhone和Retina iPad mini。
分屏多工可能還來不及在iOS 8就發表，但是很有可能跟windows 8.1 (1/4,1/2, 3/4)
一樣在iOS 8.1中做更新
太開心了～決定要不要升級iDevice做主要考量就是RAM
我的iPad3終於可以升級了
iPhone 5s就繼續等iPhone 6LS了
