My favorite piece of technology is a tablet.
I like tablets because they can do many things that computers can do, but don't have the bulk that a full size computer has. You can also listen to music, watch videos, play games, and do many other things.
The best thing is the battery life of the tablet. An average tablet has a battery life of five to six hours, which easily give you enough time to do what you need to do before your battery dies.
That is why my favorite piece of technology is the tablet.
