I'm not making an argument or anything, just pointing out an observation.

Why would a Start Screen that takes up the entire screen make sense on a laptop screen or desktop screen?

i still dont understand it... will they stop making arm tabs or will windows 9 run on those tabs?
if they dont change anything it will be the same like windows 8...

Well exactly, I like my desktop clear of clutter (8 icons total, and I rarely use any of them so could probably get rid) which is why I wouldn't use the start screen.

Windows 7 search is the equally easy.  Windows 7 is also stable, I've never had any issue with it.  I haven't noticed any changes in file copy times, so if it is faster, it not enough to be noticeable.  I prefer the Windows 7 explorer.  It sounds like you haven't used Windows 7.

So why would I upgrade to a completely new interface that makes me do everything differently, and more tablet like, when that is not what I want at all?  This is why Windows 8 bombed.  Most people weren't interested in either having to learn the new interface, or having to work around it.

W8 copy is generally faster, but its not noticable, and could easily be replicated with stronger hardware. Not to mention diminishing returns means that W8 on the same improved hardware doesn't benefit as much regardless.

It works better with handling process though.

Also this:

If you have to tell the user that they're doing it wrong, which Win 8 ethusiasts resort to time and again, then you've basically admitted that your design sucks.

I give credit to MS for being adventurous, but Win 8 is a failure on all counts. It's estranged both expert PC users and layfolk, and failed to ignite the tablet market. It's worrisome that MS feels it can make it work if it just tries harder.

this is just getting sad MS... really just quietly let yourself out the back for your own good

What there is already a second release of 8.1

I used WIndows 7 from Beta until the Beta of Windows 8 came out.  Its part of my job as a software developer.  As for completly new interface. Most of the time when I am working with my laptop I am in development tools on the Desktop and virtually no difference then Windows 7 and what has been changed are really all improvements. Use metro apps mostly when I am using my tablet, but also very handy to have my data and information available through Onedrive if I need to look at something.  

I still dont understand the oh it is so jarring to switch so I use an iPad and a Windows 7 machine.  Ok tell me that isnt jarring difference.

I think alot of people dont understand what this actually means and the op didnt cite a good article in the first place.

1- no one said the GUI for each os will be the same (they migt be, but i think desktop will be more traditional)

2-whatbthis means is a unification of the kernals, different UI's sharing the same kernal - one set of api's.

If this suceeds and it is done well, this will be amazing, programing will no longer have to be done in multiple segments for multiple OSes the only facture will be the platform and what you want it to look like on there. Having a shared library where you can add multiple UIs for the same application making it function exactly the same across all platforms but looking different depending on what you use it on.

I think alot of people are just going to hate no matter what microsoft does and alot more dont research and look around and just cry out in ignorance.

I think this might explain it better, not sure tldr: www.citeworld.com/article/2158661/development/one-windows-to-rule-them-all-its-coming-but-not-overnight.html
