One of the main motivations for quitting Microsoft 365 and adopting Google Workspace is spite, an emotion that sadly doesn’t produce a return on investment.

The source of that disappointing news is Domenico Scriva, a senior principal analyst at Gartner, who told the firm’s IT Symposium event in Australia that moving between the suites is also unlikely to save buyers much money.

He pointed out that Google Workspace licenses are cheaper than the E5 bundle that is Microsoft’s most popular M365 license, but that Google’s suite doesn’t cover telephony, security, business intelligence, or an OS license.

By the time users add all those bits to Google Workspace, he thinks they will pay $2 a month more than the cost of Microsoft’s suite – even after considering the fact that Google bundles its Gemini AI with Workspaces but Microsoft charges extra for Copilot.

Scriva said Google’s suite can be more cost effective when paired with an Apple Mac or Chromebook. Mac users get lower costs because their machines last longer than PCs, while Chromebook owners save on hardware purchase price but need to replace their machines more often.

Those numbers don’t consider the complexity of migrating between the suites, and the cost of moving. Scriva said dependencies built into either ecosystem are a likely source of migration complication, and the need for user training is another element that those who contemplate migrations sometimes neglect.

The analyst said he’s seen some M365 users trying to use the threat of migration as a negotiating tactic when renewing their Microsoft deals. He said that won’t work if you leave it too late, because Microsoft knows it’s not possible to make the move quickly.

He therefore advised starting work on a migration almost as soon as you sign a three-year M365 deal, because it takes at least two years to get it done.

If you do decide to move, he recommended having a specific outcome in mind, rather than just swapping one suite for another.

Productivity suites have scarcely changed in 30 years, he said, so it’s currently hard to see an outcome that makes a move worthwhile.

Happily, Scriva thinks AI may soon change that. He thinks we’re in a new wave of development of productivity suites in which AI assists with content creation. An imminent third wave, he predicted, will properly shake up the market by removing the need to use individual apps like word processors or presentation graphics packages, which he thinks will be replaced by some kind of AI interface that allows users to express what they want to do and then sit back and watch as their suite has a crack at the job.
