I received my iPad for week and it really creates a new learning experience to me. For social networking and Internet browsing, it is really the most convenient tool I ever used, on condition to wi fi connection.In reading e-mail, all attached MS office document are readable. with it's big screen, iPhone can't be compaired. At the same time, with some freeware, I can convert all my must-be-reading papers into ebook format, which can be viewed and annotated by iBook apps. It is meaningless that if I can only view but not making any highlight of important points. In addition, all iBook files are linked to google search and wikipidia. While reading, just double click a word, automatically you can search either google or wikipedia on the meaning or background information. Of course, not to mention to the so many apple apps covering various interests. With the apps, you can change iPad to whatever purposes you like.
