I've found while getting FC4 to work on my Acer Aspire 3023 WLMi that it has a few quirks that might be irritating (depending on how easily irritated you are), and which are related more to FC4 generally than to FC4 on the 3023 WLMi.
For whatever reason, FC4 doesn't seem to fully implement the locale preference set during installation. It gets the keyboard right (set in /etc/X11/xorg.conf), but date formats and things get a bit mixed up around the place. Thunderbird downloaded all my Gmail through POP, but was confused about the date format and sorted everything by month then date. Running Desktop->System Settings->Language didn't help because no options were offered to fix the problem.
The solution is to manually edit /etc/sysconfig/i18n like so:
LANG="en_GB.UTF-8" SYSFONT="latarcyrheb-sun16" SUPPORTED="en_GB.UTF-8:en_GB:en" LC_CTYPE="en_GB.UTF-8" LC_NUMERIC="en_GB.UTF-8" LC_TIME="en_GB.UTF-8" LC_COLLATE="en_GB.UTF-8" LC_MONETARY="en_GB.UTF-8" LC_MESSAGES="en_GB.UTF-8" LC_PAPER="en_GB.UTF-8" LC_NAME="en_GB.UTF-8" LC_ADDRESS="en_GB.UTF-8" LC_TELEPHONE="en_GB.UTF-8" LC_MEASUREMENT="en_GB.UTF-8" LC_IDENTIFICATION="en_GB.UTF-8"
Now my mail is listed in the correct order. Presumably you can substitute your own locale code for en_GB if you are elsewhere. You can also set the system default language prior to login using the button on the bottom left of the graphical login screen.
