Ok, so how's the memory usage compare when I have 50-60 tabs open until I take time to go through and grab what I needed from them? What's the comparison look like when I open (of course) the daily comics in the morning by Ctrl-clicking on the appropriate bookmarks folder to open all of them at once? I've watched that one bring misconfigured routers to their knees.
