...has been known for centuries. Biometric do not work like stupid politicians want it work.

Icons work because we have learned what the symbol means not because the symbol makes sense. Red Cross and the biohazard sign are examples of this.
If you change the symbol you have to learn everybody the meaning of the new symbol instead of just learning children the meaning of the old one.
Furthermore you don't have any guarantee that the shiny new symbol will be meaningful in a couple of years.

You buy yourself a brand new car... but the car has Good Year tires and you prefer Michelin tires, what do you do ? You sell Good Year tires and buy Michelin tires.
You buy a brand new PC... you do not want Windows so you sell... oh wait... you can't sell your Windows, can you... got the point.
As long as the anti competitive and almost illegal practice continues nobody will try to put anything else on a brand new PC.

It got superseeded by HTML5 which must be an acronym for web 3.5

"If you want to use a browser (which is the prime example of client software) on a server you are an idiot"
No sir, You are. A Terminal Server or XenApp Server do have the need for all kind of user software including a browser.
Before you speak you probably should ask yourself: "What do we try to do here".

Who was speaking of a large network here ? The Windows 7 is a pita (but far better than Vista) in stand alone mode.
We don't do Windows clients in our corporate network... far too much work to maintain, we use Linux and OS X,
Windows applications are running on 4 large Citrix XenApp servers.
I'm maintaining 4 servers instead of 120 PC, I must be stupid.

"The real question is, can Windows 7 run properly?"
Nope, it keeps asking me for admin password all the time. ...and on Windows servers it became next to impossible to use a browser.

Tits or GTFO!

You are looking at the wrong end of the problem, the client is not the real problem... The real problem is the infrastructure which is expensive to obtain and maintain.
Skype runs servers in almost all countries, servers that provides SkypeOut and SkypeIn calls for a local fee, a free alternative would need that kind of service too.

Nope... 802.11n may either run on 2.4GHz (b/gn) or 5GHz (an) but needs dual radios to run on both frequencies on the same time.
True dual band AP's are quite expensive, even switchable band AP's cost much more than b/gn AP's: a Zyxel NWA-3166 has a list price of USD 200.
