Yep, I have been buying cellular-capable iPads over the years, but only signing up for cell service on a month-to-month basis if I need it. Very nice to have when going on vacation or a ski trip and WiFi isn't available. A side benefit is that the cellular-capable iPads also include GPS hardware, which is useful in a lot of situations (don't need cellular data for GPS to work, but it speeds up satellite fixes). I am a mobile developer and now focus on iOS exclusively. I did some tablet development for BlackBerry (PlayBook) and Android (various models) and they just never came close to the iPad in terms of user friendliness, apps, or overall capability. I totally understand the comments about iOS 8 on your iPhone 4S. Whenever the yearly iOS updates come out, the oldest devices on the list almost always feel like they are crippled. Happens every darn time. I would not run iOS 8 on anything older than an iPhone 5. In one sense, it's great that Apple still makes the latest OS and security updates available for a three year old device, but it's a sure bet it will strain the older devices.
