I think Tim goes a little too far. Sometimes corporate paraphernalia can be neat, especially if you work for the company. Some guy down the road won't be interested in a BofA coffee mug, but the proud company-man might. I have a few tchotchkes from jobs past and although I don't treasure them dearly they do hold memories.
Also, if a corporation implodes in a sufficiently spectacular manner (think: Lehman Brothers), its crap may be blessed with a second life among ironic hipster types. Not that this is Bank of America's aim, I'm sure.
