@Fishman - My point EXACTLY about Mojave and Vista in general.
"Do a real experiment. Put Vista on a box, let them use it for a month, and then put XP back on it. See if they want to switch back to Vista."
Haven't bother to watch the Mojave videos (I have a severe allergy to MS marketing drivel) but I'm assuming they allowed the users to do little outside the pre-installed confines but go onto the Internet, look at their favorite sites and check their e-mail. A public kiosk is a lousy way to conduct such and experiment, because even the luser-est of families uses their computer as more than a dummy terminal for teh Interwebs.
Did they let Mom and Dad open up Quicken/Money/whatever or even go onto their Online Banking? (the scourge of IE7 and Norton alike - I've fielded too many tech calls where somebody's Online Banking was jacked up because of IE7 or some firewall)
Did they let older brother, whom we'll call Jason, install and play his copy of Doom III / Crysis / Insert Hot New FPS With Whizzy Graphics Here Tournament Edition?
Did they even try to install little sibling Sequoia's copy of Reader Rabbit (or whatever poorly programmed edutainment software the kids play with these days)?
My guess is a big, steaming pile of "Nopity nope nope" to all of the above.
ANY OS - XP, Vista, Linux, OSX, hell even OS/2 - works like a trooper if you use it in the mental confines that the creators expect you to. (i.e. never installing any 3rd party software because you don't NEED any of course, never poking your nose around in the Big Bad Control Panel or other settings area, never installing a printer, scanner, or other peripheral that isn't an optical mouse, never going to any website that isn't Google, Hotmail, Facebook or the like, etc.)
This having been ranted, Nat the IT Guy is sticking with his typical response to Vista.
"Keep XP. Keep it until a noticable portion of the software you buy or download gives you an error message saying 'This program cannot be run under Windows XP'. Because that would be the only compelling reason to upgrade to Vista."
