is Unity 3d production ready for Orca

[Krishnakant Mane]

Dear all,
I am wondering if Ubuntu-gnome is the only option for serious use of 
latest Orca.
What I mean to ask is if Ubuntu 14.04 can be used very well with it's 
dea pfault Unity 3d system?
Is it as good as the old Unity 2d?
I had asked a few questions about gnome shell and I still don't seem to 
find a way around things like notifications when for example pen drive 
is inserted or wifi connection is available.
I found it rather comfortable when a pen drive just opened or would be 
available in the launcher bar.
Also the fact that favorites menu is accessible with Unity with just alt 
f1 in 14.04.
I tested the live cd and on the surface it looked pretty accessible.
I see orca's performance has also improved drastically.
But I wish to know if I can just go ahead with Unity 3d for my 
production machine?
I used Sonar with gnome shell 3.6 or what ever was available on that, it 
was based on Ubuntu 13.10.
Has Ubuntu 14.04 gnome version taken an updated gnome-shell version than 
13.10?
If yes then may be my impressions about Gnome-shell are outdated.
So could some one kindly clear my doubts?
Happy hacking
Krishnakant.
