Technology has really expanded over 30 years

WOW! I just read an article for Computer Applications that compared a new computer that just came out to a 30 year old computer. Technology has really grown. I don't think they had blogging 30 years ago. Computers were expensive and mainly for storing important documents. Now they are still used to process documents, but are also used for so much more like entertainment, keeping in touch with friends, and seeing and learning about the world right from your home. They have also changed sizes. The newest are easy to transport and all wireless while the old is hooked up to stay. Who know where technology will be in 30 years?
