We are a Mac only house.
The boys have an iMac in their study area, and we have one in our general living space as well. Both are their large screen models.
I have my Macbook Pro, and my wife has her Powerbook which work fine as well with Safari. These are our professional computers, so they see about zero use on BF, but work very well with our home wifi.
My iPhone works fine with BF, although small pics and in-putting text are a bit of a pain.
When I travel though, I tend to take "my" iPad and that works great with BF.
I use Chrome, Firefox, and Safari of course.
Chrome is the fastest with our broadband access, but all three work equally well.
The only thing that stinks with the iPad is the lack of Flash. That bugs me.
