As said earlier, you don't want to be abandoning what works for you and investing into Windows 8 but if you have an equal choice then once again, I will copy-paste it for you instead of just saying how this thread is going in circles:
For most people there is no reason to ditch 7 and go 8, but given an equal choice where you can choose one or the other and it doesn't matter to you which one over the other, then the question to me becomes why not. Besides "little things" you may or may not notice after a bit of use, you do have an option to hook up a touch screen device, they may go on sale, you may get one and then you will have the option (just an option) to make full use if it.
Depending on how you set things up, it has been said that if you install everything identical on Windows 7 vs Windows 8, that Windows 8 will boot faster. People say no it doesn't but 99% do not have an identical dual boot to prove it. I have a quadruple boot and Windows 8 is faster to boot.
MS claims better multi monitor support, better support for connecting your HD TV in addition to your PC monitor. They also claim better security. But Comodo Firewall Freeware / Avira Antivirus Freeware and disabling Windows Firewall etc. is what I do. But still, that is a bonus.
Metro apps... you may never use. But hey, you have the option of installing a Metro App. SHIFT+CLICK on your start menu and there's your Metro. We are all in agreement that Metro by default needs to be killed for business machines, but I like the idea of being able to have an option to use it, maybe one day MS Store will have a Metro App worth trying? Right now only in their dreams
but hey maybe one day and then we get to use it on Windows 8 because we have that option.
There's this whole SkyDrive storage thing I will never use but hey, I have the option. They claim some RAM and CPU usage advantages, I haven't tested any of that, but again, if it's true then I have that as a bonus. Plus remember, we get to use our Windows 7 / Windows XP interface because of
http://sourceforge.net/projects/classicshell/files/ so there is no GUI downside.
I've also heard of several other things like Hyper-V and Windows-To-Go. I heard of NFC, something about digital financial transactions.
etc. etc. But really here's the deal:
"Everyone" was always hating on Windows 8 because of Metro. From the moment I first heard of the Metro concept, there was no doubt in my mind that we would find a way to destroy that thing the moment we install Windows 8 Final and have a Windows 7-looking Desktop while keeping all the advantages of Windows 8, regardless of what they are or whether we really need them. I disabled Metro manually, without using Classic Shell at first just to see if it could be done and it worked. But Classic Shell is easier.
So I always asked people from the get-go, why are you
even talking about Metro? You know by the time Windows 8 Final comes out, there will be a way to get rid of it? What are other reasons for not using 8?
Some of them claimed certain things work under Windows 7 whereas they do not under Windows 8. I have not had anything not work under Windows 8 (that worked on 7). Besides, it is always a good idea to install Windows XP 32-Bit on a separate partition and simply reboot into it to have the option of using ALL older software/hardware should you ever need to. But if something you use does not work under Windows 8, but it does work under Windows 7- I see that as the only legitimate reason that I know of for not going with 8 (given an equal choice).
