Wise Harry McCracken notes it's pretty easy to switch away from almost any Google service and find a replacement, a major difference from the situation with Microsoft's programs back in the 1990s.
That's nothing like the bad old days of Microsoft's ubermonopoly over PC operating systems, browsers, and office suites. Back then, important applications ran only on Windows, major sites required IE, and the documents that your pals created in Office might or might not open up properly in suites such as WordPerfect and StarOffice. All of that made it tough to opt out of Bill Gates' world even if you preferred not to be part of it.
