Testing in 64-bit vs. 32-bit

[Shane Fagan]

Hi Lee,

In the ubuntu world System 76 and zareason prefer ship 64 bit systems.
Most systems will have to move over to 64bit very soon because the
address space problem. Have a look at the wiki
http://en.wikipedia.org/wiki/64-bit 
The one good thing ubuntu developers do is use python which isnt
architecture specific. So most of the userspace applications
update-manager, ubuntu software center, computer janitor... all dont
need to be tested on every platform. 
The market value for 64bit linux?? Its just a change in the address
space so its not too much different than the 32 bit kernel in any case.
If you want the value of the linux kernel its worth about 3 billion in a
proprietary environment according to the European union :)
