I just installed the heron on an external drive and I like it. It is fast, clean and easy so far. Running noticeably faster than my 7.10 installation, although it isn't really fair to compare a clean install to an old one.
My home computer is rock-solid with Feisty, but locks up within 10 minutes of booting Hardy. And I'm not the only one. Browsing the Ubuntu general help forum gives me the impression that Ubuntu is having some growing pains. The questions and problems posted just yesterday go back for 20 pages. Not an auspicious start for what is supposed to be a Long Term Service release. [ May 02, 2008: Message edited by: Joe Ess ]
I recently just upgraded my Ubuntu from 7.10 to 8.04. I don't agree that Ubuntu 8.04 is faster than its previous releases. To me, Ubuntu 7.10 is still faster than Ubuntu 8.04, especially when Compiz is turned on. But overall, I'm quite satisfied with Ubuntu 8.04

I upgraded both my laptops to hardy via the dist-upgrade method without a hitch. Both running great. I think some things are faster. Its definitely not any slower than gutsy so I am fine with that.
Upgraded last week, with no problems so far. Starting to like Ubuntu a lot to, as it seems to 'just work'. This is what I need as I really have not the time (or interest) to any admin.
Noticed that you can also install Netbeans using the package manager - cool.
One thing I don't like the they way they discourage you from using the root user, with all this sudo carry on. Of course a quick edit of the passwd file and it’s fixed.
