Subject: What's up with 64 bit Linux
I tried installing 64-bit Ubuntu desktop just because I could and
discovered:

It takes a lot longer to launch.
Firefox doesn't work, at least not out of the box.
Gnome won't mount WebDAV shares.

So out of curiosity I went to the web to find out a little about 64-
bit OSes and this seems to be the conventional wisdom:

There are no advantages to 64-bit OSes that offset the losses from
bigger code due to bigger pointers and integers
There are classes of applications that can really benefit from 64-
bithood, especially those that memory map big files.
32-bit OSes can be written to support 64-bit applications at least on
Intel and PowerPC.

So why is Linux moving in the direction of separate 32-bit and 64-bit
builds? Is it just to remain portable on less popular hardware?
