Much of the lock-in to Wintel is in the form of applications that are only available on that platform: depend on the app – depend on the platform.
There is a news item about a medium-sized business finding that Wintel did not scale for them. They were using Excel spreadsheets to micromanage everything and it did not scale. It was not that they could not build a big enough spreadsheet or that a PC could not run the spreadsheet but it was true that the application itself was a bottleneck. They needed 100+ people to interact with the data from everywhere. That was their business model. M$’s business model was that features would be added to Excel ad nauseam to keep users locked-in to Wintel.
At the same time that a web interface was contemplated it was realized that the IT department was already congested. It made sense to shop around for a cloudy solution and it did not have to come from M$.
Other businesses likely have similar situations. It does not pay to re-invent the wheel. If a cloud solution works and streamlines the organization businesses and other organizations will adopt it. Even individuals may find cloud works. It all comes down to there being less reason to stay locked-in to M$. Other equally valid solutions could involve changing to GNU/Linux with private clouds and, whatever ends up on the servers, the client systems can be small, cheaper and simpler with GNU/Linux. A business should seek to maximize its bottom line, not M$’s.
The theme of TFA is not escaping Wintel, but the effect is the same…
