I use to purchase sony cameras at garage sales. I have several sony cameras because they have two problems. First is storage. I have 3 that store pictures on 3.5-inch floppy disks. Who has a computer that uses them anymore? I have a couple more that use memory sticks that come in more than one version and are way more expensive than sd cards. Then there is the battery. I guess they could not use the standard aa or aaa batteries. They do not charge in the camera so one needs a separate charger of which there are a huge number and a lot more than I paid for the camera. I have a nephew that has a ps4 with a 500-gigabyte hard drive. It takes more than 40 gigabytes per game so one can store about a dozen games on it. I looked into buying another hard drive but they made the space for the drive smaller than standard. I am sure they need those couple of millimeters for other reasons than trying to make people buy from them. Sony does a lot to make people buy from them only and at a lot more money.
