I have an Acer PC laptop and my son has an iPad (sorry, but I don't know which version). We need to be able to send files back & forth to each other (preferably in Word). I have an older version (2002) of Word. He has Pages on his iPad. Our problem is that he cannot open some of the Word documents I send him on his iPad, using Pages. Yesterday, I sent him four documents which I had composed on my Acer, using Word 2002, and he was able to open three of them, but not the fourth one. All four were composed on the same computer (mine) using the same program (Word 2002). And when I checked "Properties" of the four documents, they all showed that they are indeed Word documents. On his end, he was using the same iPad with the same app (Pages). So why would one of them open, yet not the other three? Any ideas? I'm stumped, although that's not saying much, as I'm certainly no computer whiz. Any help would be greatly appreciated. Oh, a final question: Is there a better app for him to use on his iPad than Pages? Would it not simplify things a lot, if we could find a version of Word for the iPad, thus making our communications more consistent/parallel/"interfaceable"?
