Support for Various Mobile Devices Clarified
To further explain how the XLP-iPhone-A5 files may work well on a variety of mobile devices, the following is now included on the 3-Line Material on the iPhone and the iPod touch page:
It appears that more and more, the 3-line and pinyin PDF files will be used on computers, including mobile devices such as the iPhone, the iPod touch, and the iPad, rather than printed out on paper. The files named with “XLP-iPhone-A5” have the same content as the regular files, but they use A5 as the paper size. They are especially suited for display on devices such as the iPhone, the iPod touch, and other devices with similarly sized screens, such as Android phones.
The XLP-iPhone-A5 files should also be a good fit on 6" (15.2 cm) screen Kindles and other similarly sized devices, as well as on tablets with 7" (17.8 cm) screens, as long as these devices have PDF support. (Note that landscape orientation may work best, as explained below.) Some may prefer to use these files on larger mobile devices like the Kindle DX or the iPad as well.
Of course, while the XLP-iPhone-A5 files will be easier to read on mobile devices than the files that use A4/Letter as the paper size, the latter are able to fit more information onto each page—the XLP-iPhone-A5 files just give you more options as you decide which text size/screen size/device orientation/file navigation ease combination works best for you.
