Oh wow! It has evolved for sure! LOL
I would say I used it first in school. Macs and IBMs were popular in the 90s for school use. I studied Dos and Linux Operating Systems in college. I was getting my associates in Accounting and I remember mostly everything written in journal form. I had one class out of my two year degree that was based on accounting for computers. My other computer class was Intro to Computers.
My first computers were an old IBM and an iMac Bondi Blue and I was using very slow dial up internet. On these computers I enjoyed games and solitare and then I found chat rooms and did some yahoo and aol chat. Found B-F.com then Myspace and LiveJournal. LOL and all is history from there. BFP and FB - the future. Had a couple other mac computers since and a couple different lap tops and love wireless internet now! I've owned some websites and learned some PHP and HTML. I got my bachelors degree all online! I've been able to chat with people around the world and interact virtually. My jobs since I got out of high school have involved using various computer programs, email, spreadsheets, power point, etc. I am able to interact with both clients and my bosses through the internet and computer emails and calendars. I am amazed with how it all has evolved and how phones play a huge role in internet connection now. Next, I would like to possibly start a business on FB and learn some phone applications and widgets.
