In any case, this week's discussion about the official unveiling of iCloud and how it compares to other, more established cloud providers, does seem to prove one point: we're just at the beginning of the "post-PC" era, in which your data becomes the important factor and the device devolves into just a means of access.
As this new vision of computing evolves, it's noteworthy that the two companies leading the way are Apple and Google. Both are creating mobile technology that is influential and are defining the ways in which we store, share and work with our ever-growing set of personal and professional data. Perhaps the term post-PC is particularly accurate, and a bit ironic, given that Microsoft, with its ties to conventional computing, seems to be relegated to a background role despite its efforts with Windows Phone 7 and Office 365, which launches this summer.
Then again, we're only in the first inning of this new ball game.
