I am considering purchasing your New American Standard w/ Strongs bible.  One question though, am I able to switch between the strongs numbers appearing for study and then also reading the text without the numbers for casual purposes?  I would not want to read the bible and work through all the strongs if I was not "studying" a word.  Thanks for your help!

Absolutely.  The new "Settings" screen has new toggles for strongs numbers and translation notes.  You can turn the numbers off so they won't appear.  You can also turn off the special translation notes (which appear as an asterisk within the text) as well.
