That is something we retailers have been saying for years, "Just give us something simple our users can use and we'll support you" but it falls on deaf ears. too many including devs in the community wear obtuse and fiddly like badges of honor, like you have to "earn" the right to use their precious OS. Look at the flame wars all over the net when that article came out that said that maybe, just maybe, CLI should be kept for servers while GUIs should be the order of the day for home users.
What we retailers need is SIMPLE, something our users can just plug in and go and Linux is so far from that it isn't even funny. sure it works OOTB...until you apply the updates, then the drivers break and its welcome to forum hunts. Ubuntu is one of the worst because while it was SUPPOSED to be for average folks they always went so bleeding edge their CDs might as well have had stigmata and their LTS are anything but, you might as well be handed a sheet that says "These are all the problems you have now that won't be fixed until you leave LTS!" because all the bug fixes end up in version + 1.
Its sad, that's what it is, to see MSFT practically handing a second free shot to FOSS with the cell phone OS mess that is Win 8 only for nobody to be willing to step up and take those customers. Instead they will continue to believe the delusion that inside every Suzy the checkout girl there is a bash programmer waiting to come out and if only Suzy would embrace the "power" of CLI like its the fricking force the world would be kittens and pie. Instead Suzy will stick with win 7 or buy an iPad and things just never get any better.
