My first personal cell phone was a 7! It was expensive and I used "Take Me Out To the Ball Game" as my ringtone. My mom loved it when I visited her and it rang!
At work I had an 11 as my first work phone. We had a Blackberry Enterprise Server to keep our data secure. It was a great work phone, except you were always "available" 24/7! I never had personal phone numbers or emails on my Blackberry. I carried my "own" phone for personal stuff.
When I left my full time job, my replacement was a single mother with two boys. When I was training her, she got called into the manager's office. I never thought anything about it until she came out very upset. She was told "if you get an email, even at home, we are support, you must answer it within two hours". The email came in on her drive home. She made dinner, helped the two children with their homework and put them to bed. She answered it around 9ish. Her manager's boss was a mom too, and I told her to go and speak to her. There is no way anyone should be told to answer an email in two hours, after working an eight hour day. A directive came down and that "two hour rule" got thrown out with the trash!
Email made mail a lot faster and mobile phones make everyone always available! The times they changed in the 1990s!
