Yes, I think the situation has changed now. I'm looking forward to good Linux-friendly ARM boxes being available for $100-$150, preinstalled with Ubuntu or Elementary OS. It won't be long until something like that would be satisfactory for most casual users. There are lots of people currently who are using XP or Vista, or old hardware which has worked fine up to now, but which periodically falls off the wagon. They have screens and keyboards, don't need perfect Office compatibility, mostly use the web, and don't particularly want to spend a lot of money for a replacement.
I am curious about the long term effects of this. We still exist in a world where many people believe the most efficient way to work with numbers is through an excel (no matter the form of the numbers).
One company I worked at 3 or 4 years did payroll for about 35,000 people in an excel spreadsheet. It mail merged and spat out checks in a process that handled about 1,000 an hour. A few times Excel hung and paychecks were late. They simply didn't know or want to accept that any of the plethora of open source databases could be made to do similar but finish payroll in an ten minutes (sans printing) instead of day and half.
And then of course obligatory XKCD: https://xkcd.com/1667/
From what I've heard of other Office products, I think the hard part would be keeping my sanity.
I know this because we tried it, and it was complete pain in the ass to continuously adapt our "Excel replacing" applications to rapidly changing business/analytics/reporting requirements.
The difference wasn't really the linux desktop itself. There never was a "year of the linux desktop". It seems to be everything else. The webification of everything slew the desktop native app and the ubiquity of a gazillion different smartphones primed people to accept new UI experiences.
The business world is finally coming out of the place where everything it does has to be rammed through the Office/Excel/Powerpoint/Exchange funnel no matter how it distorts the outcome.
