"After downloading Ubuntu 11.10 Oneiric Ocelot Alpha 2 ISO,
which is about 714 MB in size, I used UNetBootin to install it in
my USB drive for testing. This is the safest way to experience
bleeding edge versions of any Linux distro IMO. There is even a
Startup Disk Creator application by default in Ubuntu if you don't
like UNetBootin. But for me, UNetBootin has generally been the
faster and trouble-free choice of the two.
"One of the first things I noticed about the new Ubuntu 11.10
Alpha 2 was that, its a little more snappier than the previous
iterations of Unity. Dash loads a lot more faster than it used to
be and there is general 'sense of urgency', if I may call it so,
with the way Unity UI responds now."
