"Well you are entitled to your opinion as well as i am to mine"
You most certainly are, but outspoken criticism sometimes interests readers enough to require an explanation. IMO, Windows 8 received bad press, and got hung from the start, by broad, unexplained, remarks, from "trusted" sources..
"the metro screen sucks without touch"
Why? The procedure, with a mouse, is so close to similarity.
"it is very frustrating to get around the metro screen especially going back and forth on the slider with a mouse ".
What slider? It is precisely the same, with or without a mouse - a sweep across the screen. I agree with you that it can be annoying when you accidentally click the corner and the idiot "Charms" bar pops up. Such irritants have, however, been prevalent in various ways, in several previous OSs. It didn't take me too long to be a little more cautious and, for the most part, avoid the occurrence.
FWIW. Just wanted to add. Windows 8 was innovative, as was Windows Vista/7 before it, and, because of that may also fail, as did Vista. But, as I see it, without the new "Modern GUI" , I honestly do not consider that Windows 8 offered enough, over Windows 7, to warrant an entire, and expensive, new OS.
Your point regarding projection is well taken, but, surely, this is a minority concept and not a consideration for condemning an entire OS. Touch screens for projection and demonstration have been around long before Windows 8 became a reality.
It is an opinion, I know so well, but, with a customised Modern GUI, I find it easier and faster to select and use programs than I ever did with that very lengthy (also customised) legacy start menu, together with its multi sub folders.
