Apostrophe or not?

0Both are acceptable (to some/many?) unfortunately, but the reasonable one IMO is the one with PCs and PDAs. 0-

0Well, let's discuss what apostrophes are for: 02br

00Showing possession (That is Samantha's pencil.)02br
02br
00Showing that letters are missing...used in a contraction (can't, don't, won't)02br
