Hi. I have a spare off the shelf consumer PC and was thinking about loading
Solaris on it for a development box since I use Studio @work and like it
better than gcc. I was thinking maybe it isn't so smart to use ZFS since it
has only one drive. If ZFS detects something bad it might kernel panic and
lose the whole system right? I realize UFS /might/ be ignorant of any
corruption but it might be more usable and go happily on it's way without
noticing? Except then I have to size all the partitions and lose out on
compression etc. Any suggestions thankfully received.

If you are using Solaris 11 or any of the Illumos based distributions you have not choice you must use ZFS as your root/boot filesystem.

I would recommend that if physically possible attach a second drive to make it a mirror.

Personally I've run many many builds of Solaris on single disk laptop systems and never has it lost me access to my data. The only time I lost access to data on a single disk system was because of total hard drive failure. I run with copies=2 set on my home directory and any datasets I store data in when on a single disk system.

However much much more importantly ZFS does not preclude the need for off system backups. Even with mirroring, and snaphots you still have to have a backup of important data elsewhere. No file system and more importantly no hardware is that good.
