I am considering buying an ipad as I head back to school, but I want to be sure it's right for me. Basically, I need to be able to do the following: download articles, write papers, research, email and social media. My biggest concern is compatability with Word/PC. I've read/heard that documents can be emailed to the ipad and worked on in that manner. What app would I need? I've also read that there may be some format changes in the document. Are they that big of a hurdle? What else do I need to consider? Input and suggestions are appreciated. Thanks in advance.
