Interestingly, it will have taken more than 8 years for 64 bit Linux to almost catch up with 32-bit Linux.
At least if we believe http://popcon.debian.org/ is a decent estimate of 64-bit Linux adoption since 2004.
To be honest, it still hasn't by-passed the number of 32 bit submissions, but almost.
Early adopters anyone? Nope, at least not among the Debian users. So indifferent.
