Disk space is abundant and cheap. These days, you can get a 2 TB hard drive for under $100 from Newegg. I remember one of my first work computers, about 10 years ago, that came with a whopping 2 GB of storage. Those days are long gone. With the move to solid state drives, though, storage space is getting smaller, at least on a single solid state drive. My MacBook Air has a 128 GB drive, which would have felt humongous even a few years ago, but now feels small compared to my Windows 7 machine.
