I looked at an article posted by the OP... How can you pull the drapes off of something that already exists? And I want to rip it apart whilst thinking out loud.
* A new peripheral management interface called Device Stage (more info about this is coming in the Windows 7 Partner Showcase at November's WinHEC 2008 conference)
Would something like this involve a registry?
* A new self-diagnosis feature called Action Center
Does it do more than Windows Defender? Microsoft's yet to make a product that can take care of itself without the need for 3rd party apps, which makes them respect the 3rd parties but doesn't say much for Microsoft.
* A new A/V control method called StreamOn
Probably running amok with DRM...
* A new animation framework
I will place a wager that it's very similar to Apple's Quartz, if not a knock-off product.
* New task bar and shell integration features
I wouldn't go that far because it looks a lot Vista...
* Multi-touch and gesture recognition
It would've been a sin for them to put this in Vista SP1, because people are not paying for SP1. This is another one of their padded reasons to get customers to buy 7.
* Improved Bluetooth support
Not a new feature and I cannot see how it's improved. But it's another padded sales booster.
* Ribbon UI akin to Office 2007 for Windows 7's applets
Yuck! Do you know how many people hate Office 2007? My high school installed it last year, I put OpenOffice on a flash drive or I will use Google Docs. The faculty hates Office 2007, they cannot find anything.
Several friends and I took an information systems class my freshman year. We all went to a testing center to take all of our Office 2003 exams to get the Microsoft Specialist Certs. Not one of us can even stand to use 2007... I see more people using OpenOffice than ever before.
