Yes Netscape is easy and I specially liked the ability to test sites in IE and FF mode (click bottom left corner). I have also never had to ask for support. Although my primary browser is IE7, I used Netscape to test sites. I received the message when I opened it a few days ago. If you open yours, you should also receive the message to upgrade to Flock. I am usually reluctant to try something too new because it may just bomb something that currently works.
On another thought, I wonder if you or Samantha use Safari (for MS Windows) which seems is becoming more and more popular.
