You do understand that it actually takes some commitment to download, install and test these "free and open public betas" right? You keep going on about them as if it's as simple as reading a page of text or something.
Isn't that what most people here are doing, reading pages of text and then forming an opinion without ever using the thing in question? Hell, it's how this very thread started off. My point here is that, if you're unable to make the commitment to give the thing a go, then why comment on it?
In order to install and test Windows 8, I' have to repartition my drive, register with Microsoft, install the new system and pray to high heaven it does nothing to damage the already installed OS. Considering the amount of information that would require restoring if it went wrong, coupled with the amount of time it would take to install in the first place, it's not something I would wish to do, so instead I read reports from people who are technically knowledgeable and have used it. When one person calls an OS 'bad' it can be taken with a pinch of salt, when large numbers say it, you have to pay attention.
This is why I never installed ME, because of bad reviews, I didn't need to use it, simply to hear the horror stories from those who had.
Personally, I see no need to upgrade from 7. It was slightly annoying when I first got it, but since then, I've found it to be a very reliable, stable and easy-to-use system most of the time.
From what I've seen and read, Windows 8 looks like what happens when you try to turn a high-spec PC into a mobile phone. Whilst I prefer Windows over Linux purely for the reason that I like the 'hand-holding' when it comes to new hardware (mostly because I'm lazy and like plug and play), I think putting too much cotton wool between the user and the system-layer of the PC itself can serve to have the opposite effect with regards to getting a machine to run at potential.
Yes, I like the fact my PC is a lot more powerful than a mobile phone, and this isn't a Special Sports Day, so I'm a bit scared with the whole 'here's an OS that means you are
all equal!' mentality.
