Well, my opinion is that having a start menu is much better than having a start screen comprised of childish looking tablet OS tiles. I can download one of the hacks which remove Metro from my view at all, but then what's the point of Windows 8 when the Metro parts are half of the OS?
I liked Windows 7, I wanted to try Windows 8 because of how much better it supposedly was performance wise, reliability wise and everything else, but thinking about it I was never craving even more performance and Windows 7 has been secure, solid and good looking. Windows 8 feels like they want me to use my computer like a tablet, or failing that I can go back to a traditional desktop view which doesn't have the start menu, instead I get taken back to that horrible looking tiled UI which was blatantly not designed to be navigated with a mouse.
The thing I'm annoyed about is that this is just my opinion, you may not care about what things look like, how nice they are to use, where things are kept and arranged, but I do, and I'm more than entitled to share my view on here without basically being told my opinion isn't valid.
I thought Windows 3.1 was childish looking compared to DOS 6.22 back in those very old days,end of the day I just adapted and excepted you will always get a few things you may not like,in most cases and that includes Win7,8 etc you can work around them.
End of the day I adapted to Windows from DOS and saw all the changes over the decades ie 3.1,95,98,XP,Vista,7,8 and adapted to all those changes however minor or major.I even adapted to a few Linux Distros too.
Metro is not an issue,you can ignore it for 99% if you make changes and customize your PC,lets face it we all do that,ie like certain things on desktop etc...you get my point,Win8 is just an hybrid OS ie extension of both Desktop and Tablet interface,really not hard to work with or ignore Metro for those that hate it,I like to think I'm a gamer and desktop user first so if I can adapt and get things within 2 clicks max anybody can,I do miss those old DOS days with loads of commands to learn and users nowadays would throw a fit on what DOS was like back then,got it so damn easy now and people still bitch and moan lol.....
Last point nobody is forcing anybody to buy Win8,you can stay with 7 or older OS and wait for 9(9 will probably be based on Win8 anyway with improved Metro,my best guess) or get left behind.
End of the day I just adapt,quite fun in some ways doing that.
Win8 a piece of cake to use and to customize.
I actually hated Win8 in beta and did miss the Start menu 7 had,but now don't miss it at all,I've all my programs within 1 or 2 clicks regardless of Metro or Desktop and I spend 99% of my time on desktop,I even customize my Metro tiles and removed ones I don't need,anything in Metro I need on desktop went there,simple as that.
I will adapt to Win9 as well,

.
There is no perfect OS,if you can except you have to adapt regardless of the OS in question things go a lot easier,I have been doing this since DOS 6.22 where did the time go lol...
