I was once asked to participate as an expert witness against a Lemelson suit--- that was in 1985 (I declined). Amazingly, this still goes on. This snake needs to be killed once and for all. The money from each licensee victim, just goes into more legal fees to screw the next victim.

For the most part, ext3 should work fine for individual users. If your were doing a lot of sound or video, you might see a performance improvement with reiserfs.
The big issue with jounalling is fast reboots after unclean shutdowns. This might happen a lot at home if you have small children (future sysadmins!). ext3 and reiserfs-v3 only journal the meta-data, ie, the structure of the FS, not the actual file data itself. But that is huge, since it essentially prevents an unrecoverable disk, and eliminates the need to completely walk the structure tree when mounting an unclean disk (fsck), very time consuming. But you can lose data on open files.

We tested latency with a complex soft real time system (~150 sched_fifo procs at various priorities, w/ rml & akpm sched/latency patches) and found ext3 to be poor, reiserfs 50% better, but jfs the best. Never tried xfs since jfs worked so well and was already in the kernel. JFS is regarded as slower, but in our tests for latencies in soft real time situations, it is far beyond ext3 or reiserfs. BTW, ext2 worked very well, too, but we need the journaling for fast recovery.
I agree. I put in flexible blue plastic conduit (at the suggestion of my electrician). It runs from all floors (basement 1, 2) to the attic where it is a bunch of open tubes. You can put anything you want in there. Each conduit is 1/2" - 3/4". Works great.
