I would never pay that fee as per previous comment. But I'm really glad there are people who do pay, they are possibly paving the way for development, small time philanthropists and Mac lovers so i can't complain. I won't download myself though because my financial condition begs discretion. Tabs sound cool, but I just press apple and the squiggly key above the tab key to browse through my windows. How could it be easier to move through windows than a single hotkey anyway which Safari does?
