Personal note

If you want to install a package that is only available in 32bit use the following option:

dpkg -i –force-architecture skype-debian_2.0.0.72-1_i386.deb

Update:

64bit is so really shiny brand new and totally unknown how could you expect to have java plugins and flash for firefox? The java bug is only 5 years old, man…. Otherwise see this Howto. No window icons though.
