However the difference is for me windows 7 needs minimal work to get the GUI to my liking, windows 8 needs a 3rd party app such as start is back as well as other tweaks to get it to run as well as windows 7, and even then there is a lack of aero, lost functions which i think cant be patched back in and bits of metro in desktop windows, eg. try loading a file extension that has no app, you get what looks like a beta metro window. Over 30 functions have been removed from windows 7 to windows 8, the start menu is just the most publicised one.
I am also curious what new SSD features windows 8 has over windows 7, leaner faster? very generic terms. On all physical machiones and VM's I have tested on windows 7 is faster. except in certian optimised situations win8 can boot very fast other then that it looks weaker to me no performance. I certianly have not found anything thats made me drop windows 7 to upgrade. hyper-v stuff looks 'interesting' but thats about it.
If windows 8 is ready to use out of the box, why are you on this thread? if you using this app then windows 8 isnt ready for you to use out of the box.
You quoted the wrong post, for the full info answering your questions in detail as I have personally experienced it you should have read post #633.
Now, understanding what that means and evaluating the importance of said improvements is a personal matter but for me they were a valid enough reason for the upgrade. Also, yes, in my personal experience, using my main and most powerful machine, Windows 8 made better use of my hardware and resulted in not only faster loading/shutting-down times but in all-around faster response times. YMMV.
As for out-of-the-box-experience, you might be lucky with your machines but with my Gigabyte Sniper G1, after a fresh windows installation absolutely nothing works out of the box. The SATA3 controller needs a driver loaded to be recognized (even harder considering that's where the old boot HDD and the SSD are connected which means they need to be loaded during install time), USB3 ports don't work, audio doesn't work and ethernet is recognized as a PowerPC cpu.Other things too need taking care of. like newer chipset drivers etc. In windows 8, simply by virtue of how new they still are, all I had to install was the BigFoot Network Manager program for the ethernet. Plus, the Windows installation itself took about a third of the time Windows 7 took to install. SiB took me a total of 1 minute to install and setup. Big whoop!
As for the "Microsoft launch propaganda" I have absolutely no idea what you are referring to so no, that's not it.
