PC Mag writes: "The latest "featurette" for Gmail, multiple inboxes, illustrates the extraordinary product development differences between Microsoft and Google.
There was a certain antic, an almost-but-not-quite-anarchic nature to the announcement by Google Software Engineer Octavian "Vivi" Costache that he had added a new Labs-based capability to the suddenly feature-rich Google Gmail. Enthused Costache, "So when I heard about Gmail Labs, I started implementing a Labs feature in my 20% time that would help me (and you!) spend less time monitoring important messages that may end up getting filtered away."
A baker who eats his own cookies, Costache noted how he uses Gmail and is "seriously into" filters and labels. I like mail filters, but have never really fallen for Gmail's unusual label concept. There are no folders in the mail app. Instead, labels allow you to categorize incoming mail in myriad ways (so one message gets multiple labels) and, almost in pivot-table style, you can view different collections of mail based on a label you choose.
