This used to be the case, but 64-bit is now no harder to configure than
32-bit. There is nothing that I can't do in 64-bit that I can do in 32-bit.
I have the latest flash, the latest kernel (2.6.34), latest graphics
drivers, the latest codecs and latest apps. Everything just works without
any fuss. My other machine is 32-bit and I find no difference.
