I work in informatics, and it just doesn't match what I see in real life, particularly in healthcare.
That said, I could see one possible way that the statistics could be skewed, and it wouldn't be lying: 99.7 percent of U.S. employer firms are classified as "Small Business". From the same document published by the Small Business Association:
"...In 2011, there were 28.2 million small businesses, and 17,700 firms with 500 employees or more. Over three-quarters of small businesses were nonemployers; this number has trended up over the past decade, while employers have been relatively flat..."
There are statistics, and damned statistics. If you look at a "business" of a single person (of which there are a huge amount) and it counts the same as a business that employs 5000 people, then, yes...it is somehow posslble.
If this is what they mean, it is wildly misleading, but...perhaps not "untruthful".
I agree with their assessment that the rollout rate for W10 within the first 2 years will be slightly better than it was for W7. Unlike the W7 upgrade, this one doesn't seem to require any hardware upgrades, and application compatibility so far seems very good. All the indications are that an upgrade from W7 to W10 should be much smoother than the jump from XP to W7. Add to that the free upgrade in the first year, and an increasing confidence the direction Microsoft's development has take under Sataya Natella.
Granted, we don't know what their methodology is that produced the figure of 60% within the first 2 years for W7, but as long as the same methodology is followed to measure the W10 penetration rate I think that 75% prediction might not be too far off the mark.
I don't know what regulatory pressure the health care field is specific to the technologies being used. I can speak to Financial Services and can tell you that a 75% penetration in 2 years in Financial Services (Banking, Trust, Hedge Funds, Retail Banking, etc..) just ain't gonna happen. We only got off of Windows XP literally as Microsoft was turning out the lights and closing the doors on it. Windows 7 for us has been in place what .... 3 years now I think?
The only way we're going to move to Windows 10 will be because the Regulators hit us with an audit point and we're required to do it. Which can happen but it's doubtful it would.
