I tried it once before. I found it to be annoying. A public place I frequent has installed it. It appears to contract viruses regularly while IE doesn't.
Now I have a new computer. I thought I'd try it again. It features some sort of download manager that is difficult to configure and sends my downloads to who knows where. I had enough.
It's gone.
I won't be trying it again.
And I just had to tell the world about it. Hello world.
