I sold all of my Sony stock and bought Canon, mostly because of the playstation 3 and Sony battery problems, actually. A market correction in Japan could hurt the portfolio no matter what Japanese stocks one holds.
I still love that Sony Bravia XBR 2 television. I hope the worry-warts lower SNE some more so I can buy back in at a good price, although getting smoked for half a billion $ in batteries can’t be good. [edited 2006-10-23 by rae – links and pics]
