Main Mac: A 2 month old, 2012 Non Retina Macbook Pro 13 inch (1TB EVO 850 SSD, 2.9GHZ i7, 8GB RAM, OSX 10.10.5/Windows 7) . I have a Asus monitor for my desk where it becomes my desktop Mac as well.
Secondary Mac: My early 2008 White Macbook (256GB OWC SSD, 2.4GHZ C2D, 6GB RAM, OSX 10.7.5/Windows 10) gets used as a Windows 10 machine and also as a Mac for various other purposes.
iPad: I have an ageing iPad 2 (64GB, 3G, iOS 8) is used mainly for light tasks (email, safari, email, twitter, Facebook, reading and a huge number of other things), but also goes to uni with me where I use it for note taking, watching lectures, research, essay writing etc.
'Work iPad' : I have an iPad Mini 2 (16GB, iOS 9) that I use to teach people how to use an iPad.
Phone: My phone is an iPhone 5 (16GB, iOS 8), used for the normal phone things, though I do use my iPad more than my phone.
Spare phone: My 'Music Phone/iPod' (no room on my main iPhone) is a 3GS (32GB, iOS 6) goes everywhere with me, and I also use it when I don't want to drop/break/loose my iPhone 5.
