I am a new iPad user. I also use an iMac & iPhone. I have found many uses already for my iPad. More than anything I miss the iPad not having a USB port. I had planned using my iPad instead of my laptop to process credit cards for my seasonal business. My card reader requires a USB port. I love the iBooks App in my iPad. But I went to the Gutenberg website, downloaded a free audiobook in mp3 format. Now I can't find where it was stored on my iPad! I hope to become better educated about the features of my iPad on this forum. Thx for having me!!!
