The Trolls are out in force today, I see.
My own experience with Windows 8 (Pro) has been overall pretty good. And take it for what it's worth, but I've been a system engineer professionally for over 2 decades, having used computers for 3 decades. I'm a huge fan of Linux of just about any type, and I work with both Microsoft & Linux based OS's professionally as well as in a hacker/hobbyist capacity.
While I'll admit Windows 8 has quite a learning curve where it comes to finding new ways to do old tasks, it's not a steep learning curve... in fact, the more I used it, the more I found myself wishing that I had touch-screens on every system in my house so I could engage with my systems in this new way. For the entire weekend, after purchasing and loading out Windows 8 Pro on my Acer Iconia W500, I had to keep stopping myself from trying to manipulate my older systems in the same way that I was manipulating my tablet.
Now, while I really like the *feel* of the interface, and even the new software keyboard (a lot), there are several things that I find irritating about Windows 8 as well, with the largest of those being the methods I've had to use to simply create desktop shortcuts to apps that weren't already populated to the start menu. Granted, it wasn't beneath my skills... just irritating, but in retrospect... I could see this being a deal-breaker for those less technically inclined. From my experience in IT, I've seen so many people that take a "throw the baby out with the bathwater" approach to their computing hardware... system becomes slow with spyware, what do they do? Fix it? No... of course not. They go buy another computer. What a waste! Just a few weeks ago, one of my private clients asked me to evaluate her PC to determine if it should be reloaded, replaced, or what... Well, this was an odd motherboard or BIOS, or something, because it refused to load from a Windows Boot Loader, but it would boot all day from grub, so I setup the system as a dual-boot config, with WinXP (owner's preference) and Ubuntu 12.04. When it came time to deliver & install the repaired system, the owner absolutely fell in love with Ubuntu. I know... a lot of people have complained about the Unity desktop, but I've worked with it extensively and tend to optimize every system that goes out my door... nothing leaves my lab with a generic load-out... it's something I'd consider unethical considering the expectations of my clientele.
This comes around full circle to prove a point however. While a large number of people don't like change when it comes to computers in general, as has been shown so many times in the past when a leap in OS technology came along, it's not altogether impossible to wean someone to a new way of doing things, provided the "wow factor" is high enough to pique their interest. Windows 8 is in my opinion, Microsoft's way of finally realizing this... to a degree. Unity wasn't well received at first, and among some... probably never will be... but this is due to a choice in esthetics, not a reflection of the quality of an OS or desktop environment release, which is really the same thing that Microsoft is now experiencing that they've finally gotten brave enough to take the risk of radical change.
Part of me wants Microsoft to fail, yet another part of me doesn't. While I've never been a fan of Microsoft's internal attitudes, development methods, and anti-competitive practices, I've got to give it to them in for their look-and-feel unification over the years with their platforms. I like some of the protocols they've developed, and even more so when Microsoft actually cooperates with others to build out protocol support for alternative Operating Systems. But look to the fiasco involving Microsoft & UEFI secure boot certificates, and its easy to see that Mickeysoft is still up to their same old tricks. On the other hand, I really like a lot of their products, and have used their OS's, Apps, and game systems for years now. In the end, the best result to me is when a middle ground is found around standards that are not governed by any particular corporation, yet benefit all who become involved. Microsoft, just like USRobotics, Sony, and several others before them, tend to like to be the setter of trends, rather than an 'also ran', so I understand the game they play, but at the end of the day.... are they any better for it? Who wins?
Regardless, Windows 8 is a decent OS, especially considering that it's the 1.0 of a whole new design path. I'm certainly happier with this release than I was with WinME or Vista.... it could have been a *lot* worse!
