This morning I installed Solaris 10 build 72 on aFusion guest OS on Mac OS X. I was surprised by the new installer application. It's a completely different experience compared to before. Frankly, the new installation program can now compete against the user-friendliness of Ubuntu.
In less than a dozen windows, I have Solaris 10 up and running. However, it would have been better if the install is completely without the console or command-line interface (only took 3 or 4 questions before the GUI kicked in).
Generally, it is a pleasant experience and if this is a taste of what is to come when Project Indiana's done, then I'd say "Let there be HackItSolaris". :)
