So far it's looking really good! The installer issues that I had before are fixed and the install went without a hitch. However, there is one bug I should mention, if you leave the password blank when creating a user, then when you get into your new install, the user was not created. Either the user should be created without a password, or the installer should not allow a blank password field.
I'd like to see the new OpenOffice.org 3.2 included in the next release (their claim at being faster is very noticeable for me). Also the OpenOffice theme in Beta3 looks terrible. It looks like a Win98 theme of some kind and does not fit in with the KDE4 environment. I remember back on Beta1 or 2 that the OpenOffice theme fit with KDE4 which was nice so something must have gone wrong with this beta?
Also, I'm not a fan of having both Koffice and OpenOffice installed at the same time. Since I use OpenOffice primarily, I don't want to deal with changing the application preferences and simply uninstalled Koffice. Perhaps an installer option (under customize software or something) would allow the user to select upon install which office suite they would like to use?
Also I miss the ability (as with previous SOHO releases) to right-click on a software package and use the Install/Upgrade/Remove options. Perhaps this can be reimplemented in KDE4?
I haven't had a whole lot of time to play with it yet, but so far things are looking good!
