The thread subject reminds me of Xerox PARC, their Palo Alto Research Center, where they spent huge amounts of money making fantastic technological things. Steve Jobs co-founder of Apple Computer, toured PARC back in the early '80's and was so impressed he pushed for the development of new Apple products based on what he saw - first the Apple Lisa (interesting, but at $10,000 it didn't sell well) and a year later the Macintosh. The thought was that Xerox blew it by not itself capitalizing more on the technology it had invented. The "ease of use" concepts from Xerox certainly influence Jobs specifically and Apple in general, and quite possibly influenced a much later and very popular Apple product, a portable MP3/digital audio player named the iPod. I can imagine a handwritten sign somewhere in Apple that says "It's the user interface, stupid!"
As for the logo, the round thing reminds me of the AT&T "Death Star" logo that showed up decades ago, and I hadn't even realized they changed/tweaked it four years ago (speaking of going lower case). This blog talks about it and has pics of the new at&t as well as the old AT&T logos, and also mentions the evolving Starbucks logo:

But other than that, for this "xerox" thing I see red with a white cross. Reminds me sort of the Red Cross? Maybe not what Xerox wants me to think?
Meanwhile twitter got their bird logo as a non-exclusive design from a stock photo site--doesn't seem to slow them down any.
Yeah, but what about the Fail Whale?
The current designer's rule is to go all lower case. Way to blend in, Xerox.
Is there a name for that? The e e cummings effect, perhaps?
Actually,I suspect making a lower-case logo makes it and the company feel more acceptable/accessible to the young and "hip" who likely text in all-lower-case, and have even learned to see a single all-upper-case word or even three-letter sequence as SHOUTING.
