The state of the PC and the modern business/home user

[FireXtol]

So where do you see the future of applications?
It seems, more and more, applications are being moved from the desktop to the web browser. This has great portability as any OS that runs a browser is now a possible client. It allows a business to run heterogeneous computer environments. It allows home users a simple way of interaction, as most users spend a large portion of their time in a web browser. There's typically no installation, besides a one time(and updates, such as Flash).

Do you think open source is a threat?
Businesses are fast moving to open source solutions, for obvious reasons. Even home users often use open source, such as FireFox. Most applications have a GPL, BSD, or otherwise open source licensed counterpart. How do you plan to compete with free?

How long do you see Microsoft as the market leader?
By many sources Windows has fallen below 90% share. If Windows continues to leak users, and open source alternatives become ever more mature and geared towards actual desktop users rather than server environments then do you see any significant reasons to why users would stick with Windows(beyond "it's what they're used to")? I find this especially relevant as Microsoft continues to make older applications obsolete/legacy supported. I mean, if people can't use what they're used to on the latest Windows, then this seems like rational for the likelihood of jumping ship. Especially if they're basically using the same open source applications, but just on a different OS.

Do you find open source knowledge valuable?
Can you use Bash? Have you ever used any open source OS? Do you know any open source frameworks? If you got a new job where they used popular free OSS, would you be ready?
