Today, Skype makes another push into the mainstream consumer electronics market: Om Malik reports that Wal-Mart will sell 9 different Skype hardware accessories. This isn't a limited or trial run -- Skype's hardware accessories will be available at all Wal-Marts; I'm guessing all U.S. locations. The retail giant will also offer $20 Skype prepaid cards. Even for someone like me who uses Skype a lot, that card would probably last me a year.
