As others have replied, I suspend regularly, getting days or maybe a
week or so of 'uptime' on my laptop before bothering to reboot (normally
kernel or X related, since i use nvidia's driver restarting X doesn't
ALWAYS work).

No, no harm noticed. What I DON'T do is suspend with many or even any
programs open (besides background daemons and stuff like
conky/rainlendar). No reason to, I'm anal that way to Alt-F4 everything
first. This has the side benefit of protecting me against a possible
non-resume (which hasn't happened in months).

Stable and safe for me. Now, talking about HIBERNATE, on the other
hand....
