Comments, none.... really, just one persons (although highly qualified) opinion.
Some was based on the RT as well, and the ability to do tasks. Guess what, it is a TABLET, not a PC!
Nielsen based his take in part on testing he conducted with a dozen experienced PC users, who were asked to complete tasks on both traditional PCs and on the Surface RT.
But testing revealed that users had serious and persistent problems figuring out what Windows RT wanted from them, and were challenged by relatively simple chores. In one test, the participants were asked to compile a list of three recommendations for a night out, send those suggestions to a friend and acknowledge the reply.
"That was enormously complicated on the Surface RT because of the single window model," said Nielsen, referring to the one-window-at-a-time UI for Windows RT apps. And even though the OS offers a split-screen mode, "None of our test users were able to make this work."
I've got iPad's and I'm sure some people would FAIL that test too!!! Hah, my wife likes to work FULL SCREEN (on a 24" display yet) and doesn't have the concept of Windows and clicking on part of it or the taskbar to move it to the top of the Z-order... anytime I want to check something on her system she closed ALL open apps... and I keep telling her she doesn't need too!!! Not taking odds she could pass that test on a PC easily.
As I've used W8 more it is W7 with some 'pain'. Pain being programs that no longer work. Pain being programs that while being installed pop and Live Tile on the Start screen too. Pain being trying to find something that has moved... or no longer exists...
One thing MS did do right I suspect is the SUPPORT model. One set of source code possibly for RT, PC, Phone, and many variants. Fix it once and you are done.
You have to think of things differently I suppose. Although RT has a keyboard, whom would use it over a PC for serious work? Storage is a problem in some respects. Why play with Live Tiles when you can do so much more on a PC? It does have its place, but I'd call the RT in the same place as an iPad, essentially as a TERMINAL, not a PC... you get your e-mail, surf the web, play some games, do some social network stuff, etc., but then I could be wrong...
Mr. Evil, send me the W8 you have, save me $40 upgrade fee!!! <VBG>
