My Favourite piece of technology

Hello! my favourite piece of technology is the Kindle, it is an electronic books reader (e-books). I got it, however it is not mine, my brother bought it last summer. I use it when I read a book and I don't know the meaning of a word, really I prefer read a ''n-book'' (normal book) but if you want a fast and able diccionary the kindle is a good choise, then I use it many times. I like this machine because it's not harmful for your eyes and have a so durable battery, not like another machines with strong lights and a short life battery for example the famous iPad.
Without this machine my life would be maybe a little slower because I'll take more time searching words on a normal diccionary and always with a less probability of found the unknown word on a outdated diccionary.
