I thought I'd toss this out there as I'm about to augment my desktop with an SSD too. Rather than trying to predict which files will be accessed most frequently or benefit most from an SSD, or risk running out of space because I failed to predict usage on a specific partition, I've been looking at unreasonably complicated solutions!
Firstly, a copy-on-write RAID1 between an SSD and hard drive partition of equal size for / and the remainder on /home. Not foolproof but should net some decent performance gains with minimal filesystem risk. I've also been looking at doing this with a RAMdisk, but with much greater risk on power loss. Secondly, for the truly masochistic, flashcache! Basically using the SSD to intelligently accelerate access to everything on the hard drive regardless of partitioning, using sophisticated logic. You don't store anything directly to the SSD, it's more like an Accelerator at that point. Getting a system to boot from an entirely flashcache integrated system has been fairly non-trivial in the past however. Facebook wrote fastcache for their server farms, and subsequently open sourced it. As I am always one for the most complicated and elegant solution possible, clearly fastcache is the approach I plan on taking.
