My original iPhone SE and Samsung Chromebook bought for $30 on eBay (with SDSU etched on the front) work perfectly for what I need them for.
I have an iPad which I bought on Craigslist and runs iOS9, and it still works great for my Web needs.
I only use it for my own websites, which I keep lightweight and accessible, and a a few others like HN.
