I would like to try Unity in desktop version. Will it be available in the Alpha 1 release?
It is planned to get Compiz 0.9.4 and Unity work together for Alpha 1 (which is a month away), so I'm pretty sure we will be able to test Unity at least via a PPA by then.
You can try the unity right now in 10.04 or 10.10.
run this in your terminal:
sudo apt-get install ubuntu-netbook
sudo apt-get install unity
after logging out you will be able to choose Ubuntu Netbook Edition
