On the contrary, I quite enjoy using Windows 8 on a non-touch screen laptop.
It doesn't feel much different to Windows 7 in general usage. Yeah there's a start screen instead of a start menu but if you make use of desktop shortcuts and taskbar pinned items then you rarely notice that there's this new touch friendly UI in front of everything.
That being said, there's not a whole lot of benefit of using Windows 8 over Windows 7. So my answer is: "Toss a coin".
I agree--I have Win8 on a desktop and will never roll back to Win7. I read all the *****ing online about how terrible Win8 is, and you know what? As I do my day to day work, I'm on my familiar desktop. All of my most-used applications are in my Quick Launch bar, at the bottom of the screen where they have been for 10+ years now. (My taskbar is two rows high--Quick Launch on the bottom, running applications top.) Everything runs and opens like it always has.
When do I go to the Win8 start screen? If I want to play a couple of the games, flip through some news, etc. (It's a nice way to get away from the distractions of the "work" on my desktop if I just want to chill for a bit.) Or, if I need to hunt down an application I sometimes have to kick back to start screen. I like the data updates on the lockscreen, but wish I could add more of them. Can't say I'm totally sold on the start screen idea, but if you want the start menu back, there are already a few add-ons out there which will add it back in. (Start8 by Stardock seems to be the best of what's out there.) And there are tweaks to boot right to the logon screen and your desktop, bypassing the start screen. They take all of a minute or two to change.
What advantages do I see? Way more keyboard shortcuts that utilize the Windows key. My most recent favorite is <Win-X>. I'm getting used to the minimalistic theme. Performance-wise I've noticed improvement all around. Some disk operations are faster now--there were often pauses or laggy behavior in Win7 that I am no longer seeing in Win8. Also, with this crap motherboard of mine, I can finally put the computer into sleep mode in Win8 and have it wake properly. The task manager has also changed, offering more ways to view running processes and services. Explorer now has a "ribbon" and while I hide it most of the time, I reveal it if I'm doing a lot of file operations since it actually does have a few useful tools on it.
I just installed Office 2013 a few days ago, and while I did have to dig a bit to find the icons to put on my Quick Launch bar (it installed things on the start screen), I'm up and rockin' now. If I reduce the ribbon to tabs and turn off rulers, there is almost no "interface" around a document, which is very nice--I like working from an uncluttered interface.
Keep in mind that underneath the new GUI, this is really just Windows NT 6.2 (Vista = 6.0, Win7 = 6.1, Win8 = 6.2...yeah, I know

). So the core of the OS is proven and solid. I was running Win7 for months without a reboot, and so far Win8 is just as solid. All my previously running background services still run--everything from my Mezzmo DLNA server to Apache and MySQL.
I'm laptop shopping. I don't necessarily want one, and to be honest I really dislike them (not as much as tablets), but I need one for school. I really like the touchscreen laptop I tried, but at a $200-$300 premium, I can't swing it. I like navigating things better in Win8 with the touchscreen than those ridiculous touchpads, and I don't really want to lug a mouse around with me either.
All the naysayers in the press just like to find anything to complain about. Day to day? I'm in my familiar desktop, and everything is where I left it before the upgrade. Other than the start screen that I don't use much, nothing has really changed all that much. It was worth a $40 upgrade fee; I upgraded for only $15, and got the free Media Center upgrade as well.
