I always immediately closed that and disabled all reporting to MS and i am sure most users who don't have 100 icons on their desktop did the same thing.
I use the start menu fairly frequently. I don't use the desktop. I think a lot of people use the pinned start menu items, well based on my experience.
I am an experienced user and am happy to allow anonymous reporting to Microsoft. It's typically paranoid people and network admins dealing with managed computers that disable it - the same people that usually disable automatic Windows updates. You certainly cannot claim to speak for all experienced users.
Yes primary applications will be on the taskbar. But most people do not pin every application on their pc to the taskbar. They pin secondary applications to their start menu for easy access.
Unless you one of those people that just IE and go to facebook and check your yahoo mail. Then you would use windows 7 in a similar way.
The taskbar is where your most used programs are pinned. I do use the Start Menu in Win7 to pin additional programs that I use less frequently but then the new metro Start Screen is much better suited to that - you can pin more apps, they have a larger area to click on, if they support Metro they can have additional notifications, they can easily be arranged through click & drag (in Win7 you have to pin them then drag them), etc. And again, you cannot dismiss everybody that uses computers differently to use as a IE / Facebook simpleton. It's completely unreasonable, baseless and childish.
They also say people like jump lists, i have never met anyone who likes jump lists working within IT. jump lists on the start menu and the taskbar are extremely annoying, at least one positive thing about the new fullscreen mess of a start menu is no jump lists.
I regularly use Jump Lists to access folders in Explorer, incognito mode in Chrome, recent games in Steam, to launch additional versions of an application, etc. You cannot claim to be an advanced user if you refuse to adapt to new features and instead live in the past. I don't think that Jump Lists are a hugely compelling feature but they are useful.
Having used the Consumer Preview for a few days now I can say that many of the new additions are incredibly welcome. The Control Panel is accessible as quickly as before by right-clicking on the bottom left of the screen, as well as quicker access to other important tools like Device Manager, Power Options, Command Prompt, Network Connections, etc. The Explorer ribbon makes it easier to operate the computer one-handed (for instance exposing the permanent delete functionality, select all and inverse selections), which is great when you're drinking a cup of tea or eating.
There's plenty that I don't like or I'm not yet used to but your complaints seem to revolve around resistance to change rather than legitimate concerns with the operating system, like the extra steps required to shut-down the computer, like the way you can't click the start popup unless you first move you mouse up the side of the screen and then back down, or the way the charm bar doesn't work at all well with multi-monitor setups. You just seem to be annoyed because you refuse to learn the new time saving functionality into Windows 8.
