Linux I'm in a bit of a pickle here. I have an Atom 330-based tiny computer which I use as my HTPC. It performed its job fine running Windows 7 and Boxee, and over the past few months, it ran Mac OS X Leopard with Plex. Now, however, I want to try Linux as an HTPC operating system, but I kind of ran into a roadblock there with Ubuntu 9.10 - so the question is: what is a good HTPC Linux distribution?

Edit:Sorry, I was wrong. Only the Z and N don't have 64bit.
But with less than 4GB 64bit is toally pointless. You waste a lot of CPU cache for nothing. The system will be way slower.

Strictly speaking, don't the kernel tradeoffs begin above around 800MB? Bounce buffers and such? And don't forget all the extra registers that come with X86_64.

Personally, I think that 64 bit kernel with 32 bit user space, with individual 64 bit apps deployed strategically, is really optimum for many situations. The kernel has all the memory management advantages of 64 bit. But without the memory hit of 64 bit user space pointers, except where 64 bit can really help. As it *which* 64 bit apps to strategically deploy, if any... I'm not certain. And, of course, it depends upon the exact situation.
