I just started using Macpup Opera on a laptop- and liked it enough to do a full install on the HD.
One question-
Is there a way to configure things so the arrows on a scroll bar are placed together at the bottom, like OS X?
Especially with a laptop and a little scroll pad, if you want to switch from scrolling up to scrolling down, it's much easier to move the cursor a few mm to change directions instead of going all the way from the top to the bottom of the scroll bar.
