I must join you here, I also caught that Apple bug. There is no antivirus for iOS so it seems that I am now stuck with it.
I have a MacBook Pro 15" that is now used as a 'desktop' since I mainly use my iPads. The Mac is used to backup my and my families iOS devices, store our photos, convert videos and backup personal content and video on external drives.
As for iOS devices, I started with the original iPhone which was not even available for purchase in my country, but it didn't stop me. I've since upgraded annually except for once when I skipped the iPhone 5s and kept my iPhone 5 for a second year. I currently have the iPhone 6s, but had the 6 Plus last time and while I am used to the 6s size now, I miss the bigger size, so I'm looking forward to an iPhone 7 Plus.
I also have an Apple Watch (stainless steel), Apple TVs 3 and 4.
The iPads that I use now are the 12.9" Pro, 9.7" Pro and mini 2. I just can't pick one size. I wish that I could. I really like the size of the 12.9" Pro for most things....web browsing, games, forums, PIP, magazines, typing, etc. I love to use it at my home computer desk and the lounge room recliner. I can also use it comfortably in bed and often take it to work with me. However, it becomes quite awkward and heavy if I leave work and go shopping. This is where the 9.7" Pro comes in. It is very portable and light. I can do everything on it that I can do on the 12.9" Pro, just on a smaller screen and it's lighter to hold with one hand. (I have rheumatoid arthritis, but I can manage with all iPad sizes by adjusting the way I hold them). Then I have the iPad mini 2. My daughter was using it for a time and I was missing it, but she was struggling with the iPad 2 not being fast and crashing on some games. So when I got the 9.7" Pro, my husband got my Air 2 and she got the Air that I had previously passed to him....so I got the mini 2 back. My thought was that I'd use it in my handbag for portability, but I haven't done so as yet, the 9.7" Pro has actually taken that role, which surprised me since I did use the mini 2 in my handbag prior to having the 12.9" Pro. It's just that the 9.7" Pro now feels so small and light after using the 12.9" Pro, that it feels like a mini now. I have the mini still fully loaded with the main apps that I use, but I have been thinking of using it more for eBooks, forum reading and light games beside my bed.
I just got the ASK today for the 12.9" Pro and this is actually my first post with it. Loving it so far. I would like the keys to be backlit and for an extra row along the top with special iPad functionality, but otherwise I find it great.
So I mainly use the 12.9" and 9.7" iPad Pros....and I love them both, but kind of wish that I didn't since I wonder each morning which one I want to take with me to work for the day and find it a difficult decision. Sometimes I have just taken both. Overkill? Yes it is, but that is why I thought I should join this thread, I can't help it, I just want them all too.
