Oh my. Let me tell you. Plenty of commercial grade very expensive Windows software is ANYTHING but easy to use. Things you pay $30,000+ per year just for support (for one machine)...and even then..it's still crap.
I'll take my open source Linux projects any day over that crap, thank you. If you're in the server world though, it's a serious contender, and often MUCH easier to accomplish tasks with compared to the Microsoft stack. But I wouldn't suggest that Linux is the best tool for most Desktop users.
Most of the websites you visit are powered by open source technology. Including this one.
That's my point, Commercial Grade requires a different set of properties than Consumer Grade. This is true of nearly anything. My issue is that they are taking a Commercial Grade product and selling it to low end consumers and then not explaining how to use it. That's like me putting you a Semi with a 15speed Eaton Box in it and not teaching you how to shift and telling you "You can go ahead and drive this to school." Unless you know how to work that transmission, you're not going to get to school, you're gonna be grinding gears trying to get out of the parking lot. You'll look in the Owners Manual and it tells you all about how to select which gear and range you want to use, but it doesn't tell you anything about how to successfully get from one gear to the next. So you come back to me in the Car Lot shack and ask "Hey, how do I shift gears in this thing?" "Well, it doesn't have synchronizer rings in the transmission, so you have to manually syncronize the RPMs you need the engine to be at for whatever your next gear is at the speed you are at.". "Well how do I figure that out?" "Well, I have a CDL course that you can take for $2500. It takes 6 weeks and we teach you how to shift, back the trailer, hire lumpers and run a trucking company." "I don't need to know all that, I just need to get to school." "Yeah, this really isn't the vehicle you want then." "Then why did you put me in it?"
Put truck drivers in trucks and put commuter drivers in cars.
This is also analogous to the question, "Can a fresh private pilot transition themselves to a 747?" The answer is "Yes, but it's gonna be an expensive and painful process the results of which may kill you..."
