If you really get into it, vim can be customized quite a bit.  You can
pick and choose what you features want installed quite in quite a bit
more detail detail than above.  The source code is at
http://ftp.at.vim.org/pub/vim/unix/vim-7.1.tar.bz2.  One problem that I
have run into is that some distros have built in X11 so that if you
build or install a system without X (something I recommend for servers),
vim won't load because it is looking for libX11.

There are some who want vim-minimal or plain plain vi for /bin in the
case of a shared /usr/bin directory.  I really don't think this is
necessary any more because disk space for executables is not the same
constraint it used to be.  For instance vim on my system is 1.6M with
the following libraries:

        linux-gate.so.1 =>  (0xffffe000)
        libgtk-x11-2.0.so.0 => /usr/lib/libgtk-x11-2.0.so.0 (0xb7c73000)

        libglib-2.0.so.0 => /usr/lib/libglib-2.0.so.0 (0xb7a10000)
        libXt.so.6 => /usr/X11R6/lib/libXt.so.6 (0xb79bf000)
        libncurses.so.5 => /lib/libncurses.so.5 (0xb797b000)

        libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0xb7790000)

        libSM.so.6 => /usr/X11R6/lib/libSM.so.6 (0xb7783000)
        libICE.so.6 => /usr/X11R6/lib/libICE.so.6 (0xb776b000)
        libXrender.so.1 => /usr/X11R6/lib/libXrender.so.1 (0xb7762000)
        libXfixes.so.3 => /usr/X11R6/lib/libXfixes.so.3 (0xb775d000)
        libXrandr.so.2 => /usr/X11R6/lib/libXrandr.so.2 (0xb7759000)
        libXinerama.so.1 => /usr/X11R6/lib/libXinerama.so.1 (0xb7756000)
        libfontconfig.so.1 => /usr/lib/libfontconfig.so.1 (0xb7727000)
        libXcursor.so.1 => /usr/X11R6/lib/libXcursor.so.1 (0xb771d000)
        libXext.so.6 => /usr/X11R6/lib/libXext.so.6 (0xb770f000)
        /lib/ld-linux.so.2 (0xb7fd4000)
        libpangoft2-1.0.so.0 => /usr/lib/libpangoft2-1.0.so.0 (0xb76e4000)
        libfreetype.so.6 => /usr/lib/libfreetype.so.6 (0xb7676000)
        libz.so.1 => /lib/libz.so.1 (0xb7662000)
        libpng12.so.0 => /usr/lib/libpng12.so.0 (0xb7626000)
        libexpat.so.0 => /usr/lib/libexpat.so.0 (0xb7606000)
        libexpat.so.1 => /usr/lib/libexpat.so.1 (0xb75e6000)


On the other hand, the vim I built for a server is 857K and is only
dependent on:

        libncurses.so.5 => /lib/libncurses.so.5 (0x40018000)
        libdl.so.2 => /lib/libdl.so.2 (0x40058000)
        libc.so.6 => /lib/libc.so.6 (0x4005b000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

Note that is it libcurses that make the arrow keys, etc work.
