Even if I did elaborate it, you won't necessarily agree with it (You've got different opinions) and it'll turn out to be worthless to write a long essay about ChromeOS > JoliOS.
I recommend you give the latest version of Hexxeh's unofficial Chrome OS a try (seeing is believing), ChromeOS Vanilla Build By Hexxeh (Unofficial)
But even after using it, if you still feel JoliOS > ChromeOS, well than that's your opinion (and mine is mine)

.
In Joli Cloud you can run even OpenOffice.org and other desktop application, can you do that in ChromeOS? At least I couldn't figure that out if you can.
Yup you can't because Google has "Google docs", a "webapp" for editing documents online (and now with support for offline storage). It is a good alternative to OpenOffice.org.
It is a WebOS, how do you expect it to run Desktop apps when it is an OS based on the internet and the cloud (which is it's purpose)
