I don't think that Google Chrome OS would be suitable for most corporate shops that are generally Microsoft centric (and have been for quite some time). I think this free OS will be geared towards light users that primarily use their computer for surfing the web and checking their email.
It sounds to me like jeffspost is over generalizing and suggesting that Google Chrome OS will only succeed if it's embraced by large corporations. The software hasn't even launched and jeffspost has already figured out it's "one missing piece".
They are launching it as a netbook OS for a reason. Netbooks is a loose term. I'm not exactly sure what the line is, but one definition might be a small laptop that doesn't replace your main computer.
I daresay that whoever buys this will either have another computer or have no need for corporate apps.
Taking another view: any Java app can be an applet (if you take care of things like access to the file system). Therefore, we already have then, since Eclipse and Netbeans can be an applet, and thus a web app. Theoretically, anyway. :-)
jeffspost notes a startup opportunity: webapps for creating webapps (actually webapp clients, but that's less memorable)
They don't need application vendors to target Chrome OS in order for this to be a success - the whole point is that it just runs web apps, period.
Its targeted at consumers and netbooks, not those that want to run heavy duty, CPU-intensive applications. The whole idea of a netbook is to be small, light, quick, and primary a web browsing device.
