Somebody had the good idea to put a camera into a cellphone. This was a good idea. It was a great idea. What made it even better was including a slot for a Micro-SD card. I have a 32-gigabyte chip in my phone and I haven’t run out of storage yet. I can shoot photos or movies wherever I go—and email them immediately. I can read e-books or listen to music or watch videos. (The Samsung Galaxy phone has a great screen.)
The smartphone is a combination of many good ideas and its overall usefulness should be a guide for all manufacturers of portable electronics. So why doesn’t the iPad have a memory card slot? Why doesn’t Amazon’s Kindle Fire have a slot for an SD card? Who knows, but here are some other good tech ideas that need to be implemented ASAP.
