Thanks to author and programmer Mike Ash for this developer-focused explanation of Apple’s move to the 64-bit A7 chip in the iPhone 5s. In short, although details will vary by app, 64-bit code that takes advantage of new programming techniques can be faster and use less memory (though 64-bit apps use more memory in general). Plus, old 32-bit code can run on the A7 with no changes or performance penalty.follow link
Stylin' a Word Comment Balloon
If you work with Word's Comment feature, you may find that the comment-balloon text is too small to work with, or you may just want some variety. To modify the style, choose Format > Style. From the List pop-up menu, choose All Styles. Select Balloon Text from the Style list. Modify the style as you like, and then click Apply. I like Arial Narrow, 12 point.
