I've not played with Ubuntu, but how much easier can it be than OSX? Drag the application icon onto the trash bin and drop it in
Applications -> Add/Remove -> Choose from repository -> Click install
that's easier than:
Web browser -> download -> zip -> dmg -> drag/drop
though that's easier than:
download source -> terminal to dir -> ./configure -> sudo make install -> bugger, my c compiler isn't up to date -> download and install c compiler -> make install again
