Some month ago, I got a Samsung Slate 7 Tablet PC on which I am using Fedora as my main OS. The only thing that bothered me a little was that the built-in e-mail client cannot be comfortably used via touch input. Thus, I compiled kdepim manually in order to get the mobile UI as well. These are the steps I did to compile kdepim with the mobile UI:

sudo yum-builddep kdepim

# Download kdepim source from http://quickgit.kde.org/?p=kdepim.git
http://quickgit.kde.org/?p=kdepim.git&a=snapshot&h=5cf4021c72d1b0986645692e3f8cab61295d2ce9&fmt=tgz

tar xf kdepim-*.tar.gz
cd kdepim
cmake -DKDEPIM_MOBILE_UI:BOOL=ON

# Only mail
#cd mobile/mail
# Other mobile as well
#cd mobile

make
sudo make install
