They have actually a good products and that is why they are still on the market right now as well as the founder.
I have used various operating systems including Windows, IOS, Fedora, and Ubuntu. I found Windows the most user friendly. For tech savvy people, Ubuntu may be better, but the vast majority of the remainder is going to chose Windows.
This is quite an outlier case. I've never seen a client wish to return to a windows environment after having a non-backdoored system, mostly just because it winds up being faster and easier to use. This is for folks of little to no technical ability.
People "choose" windows because it comes preinstalled and nobody has told them a much easier and more functional option exists. Who would tell them? There's no advertising or company to say anything. You have to be lucky enough to have somebody in your life who knows something about computers.
Well, that was before however now i can see most of the computers being sold in our place has now a Ubuntu linux operating system. Yet people still wants to reformat it becausw they use to it and you are right this is good for not on the development side of the computer
