This is from the Ubuntu Beta Release (3/30/2011)

charles@flatline:~$ unity --version
unity 3.6.8

running on an AOA150 Netbook - its "stable" until I go to interact with the unity interface. Most often it crashes on pulling the application lense/drawer (not sure which its called at this point)

http://en.wikipedia.org/wiki/Acer_Aspire_One - ZG5 for the hardware listing of the machine thats producing the errors. If theres any further information let me know and i'll post it
