And generalising that it will need to replace Windows.
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.
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".
