Yes! That is right-- forget the old Web 2.0 concept, and move onto the newer Desktop 2.0 concept. Only recently has there been chatter about it, at the CES, sometimes it's been talked about on forums, but now O'Reilly (the publishing group that created the Web 2.0 concept) is now getting abuzz with the new Desktop 2.0 concept. My ideas for this are:
Glossy Icons on all New software
Better software support for all Systems (ie Linux, BSD, Mac)
Let everything WORK together. As in, when you have systems that are different, let the software connect and work seemlessly.
More technical Support. This also means more jobs, AND DON'T SEND THEM TO CHINA OR INDIA. Keep them here, let the economy grow.
Wider range of community help. Give power to the people. Tech Support isn't always the best way. Sometimes, if you let people talk with ACTUAL USERS of the software, you could get better ideas for material.
CLOSE OPEN SOURCE. Let all software cost money! Open Source is bad, it doesn't create jobs, plus since it's a hobby, not everyone will want to contribute there great knowledge to it.

That's basically all my concepts, but also to add more stuff to my list, then doesn't work with the rant-based type.... Let there be a better Help section! I recently ran into Sony Vegas Pro 8.0a, and I have been using it/fooling around with it for a while.... And out of all of the different softwares I have ever used... it had the BEST KB (Knowledge Base) out of any programs that I have used.
Also, there should be an image included in every new software created that describes ALL of the Menus, the buttons, and what they all CAN do. It would save me a lot of time when trying to figure something out, and also help others that are "newbs" use the software easier.

Although it had started out as a guidelines for Desktop 2.0, it seems to have turned into a rant. Wish it would be more friendly... but I guess if you want to get a point across, you need to rant. :D
