Lastly, the “network effects” drum that Blodget has been banging for years is certainly a real and important factor. But modern computers — PCs, phones, tablets, all of them — are effectively just clients on one universal platform: the Internet. In the ’90s, as the Mac and Apple waned, compatibility meant connecting to Exchange servers, and reading and writing Microsoft Word, Excel, and PowerPoint files. Today, compatibility is a rarely uttered word. Twitter, Facebook, email, and at a lower level, HTTP are available to all platforms.
That's what I've been saying. I could switch to an Android phone tomorrow with minimal disruption. And vice versa.
