I miss the old pixellated Xerox logo. It was simple, distinctive, and represents exactly where Xerox is in the business world. I never understood the, "we're not a printer/copy company" line. That would like Microsoft saying, "we aren't an operating system company." Microsoft does do other things (I loves me XBox), but they're an OS company.

I've never liked the IBM logo. Design authorities who say that the negative space bands imply speed and dynamism are ignoring what the lines actually look like: scan line gaps in an ancient text-only monitor. When I think of a dated logo, the first one that comes to mind is IBM's.
