Win 8 superior? In not too many ways besides the lack of drivers still and the problems people have been running into even after a clean install with all updates on. It seems even the retail 8 is proving a bit buggy.
As for being lighter weight on resources then 7 that has to do with two main items not mentioned so far. 1) Further progress by some MS dept.s that is on the MinWin kernel brought in by 7. 2) Features commonly seen in previous versions gone! Media Center, useless form of Windows Defender, dvd and video playback support GONE! That's bound to end up seeing fewer processes running in the background as well as the increased need for 3rd party apps spelling out a losing formula!
As for bringing back the Start orb/ menu, All Programs menu, and additional Settings>Control Panel, Administrative Tools, etc. that has been centralized through the Start to begin and then scattered all over by 8 the writer there clearly points out that seeing the Start actually returned is not "written in stone" at the present moment but only hinted on.
As for the Metro or "Modern" as some have referred to it as being the MS name simply watch one of the latest Win 8 tv spots and see just what device is being used to show how "wonderful" 8 is...

with what? a tablet gui being shown on what? a tablet not any laptop or desktop! The Windows RT gui at work on a... "Tablet"!
And the Big Goober MS made besides already having the "Choice of GUI" as at least a setup option is what? Using a tablet touch&swipe on the desktop releases instead of foresight and developing a "Desktop" compatible Touch&Swipe gui everyone could adhere to! And then they wonder why 8 is not selling? daaaaaa....
As for the core elements besides stripping away at the features what could have been a good following to 7 by the ways now only sees a few new "eye candies" or "Bells & Whistles" when looking at the new Lock screen and login option of password, pin code, or pic file. The task manager also finally has a new look similar to a 3rd party benchmarking app to revitalize that while the rest of 8... STINKS! as far as the traditional form of Windows is concerned.
Now if someone is fortunate enough to see a good install, isn't running into any software problems, and has all the drivers working well their immediate thought is "This is a better Windows and even starts up faster!". At the same time they seem to forget instead of seeing things centralized for repetitive tasks things are scattered all over in hidden toolbars and right click menus! For tablet and smart phone users "No big deal!" not having been working on Windows desktops since the 90s! they don't have the "Wat's up witha this stuff eh?" type feelings about the way MS botched up the works in favor of their own new Surface tablets which is precisely why they wanted everything looking exaxtly the same across the board regardless if the desktop sales fell through entirely They only focus was promoting tablet sales since they were bringing in a new hardware product line. TADAaaaa...!!!
Can anyone comprehend the marketing strategy being deployed there? If the usual something has a hiccup every other ? then why worry if 8 tanks when you are trying to promote something entirely different in the first place in order to compete with two other giant mobile device artists? No! You want a slam dunk on the competition! MS wants a piece of the pie the Fruit basket company as well as "Gooog doodle litis" are into! Can't you smell the flowers? Blaaa... :sarc:
