This week both HP and Dell reported significantly weak PC sales. While Meg Whitman asserted that the PC was not dead, the most alive aspect in the market featured smartphones and tablets.  A quick perusal of the landscape reveals even more signs of mobility moving from a trend to a certainty.  Yesterday PayPal and Discover announced a partnership that ups the ante on the Starbucks and Square news earlier this month and adds to the momentum building for mobile payments. Three months ago, Mary Meeker presented her analysis of the Internet at the D: All Things Digital conference ion California. While her presentation in its entirety is well worth the strong impact it continues to make, one particular slide really hit home (see below). For years people have talked about working from home versus working from the office. But the mobility tsunami is so much more than that.  We are rapidly approaching the point where we can choose to work, learn, play connect or do from where we want to be, not where we have to be. And as we become increasingly untethered, a chosen place will need to be much more than its simple physicality to be highly valued by its occupants.

update: One more note of mobility challenging previous practice – Facebook and ads

Goodbye to being tethered?
