Thanks to modern technology, it really made our lives easier and lighter. lol. Do you remember the first computers, they were very huge and will occupy almost the whole room for just one computer. But now looked at them, you can hold them in the palm your hand like the I-pads and netbooks. And with the invention of digital storage like micro sd you can store all your files in one small chip unlike before you need a big filing cabinet to store all those data. Just insert this micro sd in your computer and you can store as many data as you like and you can carry it anywhere you go.
