I know how many are saying the iphone Plus makes the iPad mini obsolete...but I still think the mini is the perfect iPad size. As big as the iPhone Plus is...the mini just makes web surfing and content creation that much easier. It's also more portable than either the 9.7" iPad pro or the 12.9" iPad pro. I can fit the mini in my cargo pants pocket. I'm grandfathered in on the original Att unlimited data plan for the iPad. After the original iPad, I just kept buying new iPad minis. It's the perfect size, at least for me. I hope Apple keeps it in the lineup. If not, I wonder if I can put my iPad mini micro sim in a new iPhone 7 plus? Hmmm?
I'm in the same situation. I have an iPhone 6 Plus and an iPad Mini and love both. I obviously use the iPhone when out of the house, but I grab the iPad mini when home. I had an iPad 9.7" for years, I have found the iPad mini to be the perfect size for everyday use. It's perfect for ebook reading, browsing internet, watching Netflix, traveling, games. I hope they don't discontinue it.
