The new version 6 of Apple's iOS operating system for iPhones and iPads features strong Facebook integration, local search and mapping. That could wipe out many internet start-ups, and even threaten major players.
"It marks the end, I think, of some of the business models of many start-ups," said Chris Stevenson, chief technology officer of mobile application-development firm 955 Dreams, shortly after Apple's keynote.
"One of the things they announced as part of the Maps application is that Apple have built their own location-based search, and of course that hits right at the core of Google's business model," he said.
"It's pretty scary if you care about open systems, if you care about being able to use the products of your choice."
As Patrick Collison, co-founder of payments services company Stripe, said via Twitter, "It's hard to think of large tech companies that shouldn't feel worried."
On this week's Patch Monday podcast, we hear Stevenson's reactions to Apple's announcements in full, as well as those of applications architect Benno Rice.
"We've sort of entered this phase of homesteading, where the Wild West frontier got opened up, and now everyone's trying to build fences around sections of it as madly as they can," Rice said.
"It seems like everyone is scared of Google, because I think they see Google as the company who could come around behind them, because they've done that before."
