Never, unless there's a horrible issue. My Powerbook has been running since 2003, and the Classic has been going since 1992.
I seem to recall you being the person talking about how Windows isn't that bad if you maintain it well, maybe you should extend the same treatment to your Mac. Download Onyx, read the help files and run the maintenance that seems most useful.
This may be the opportune time for a little rant.
I
do try and extend the same treatment to my Macs - but they invariably seem to need
far more care to be anywhere near as stable. Unlike someone upgrading with relief from a superannuated and close-to-death PC to a brand new Mac, I run equipment as up to date on the Windows side.
I have had to dig out the OS DVD a few times last and this year to fix boot disc problems for example, perhaps caused by the frequent once a fortnight - once a month (depending on the use of the machine in question) forced shutdowns due to GCODs. I've spent multitudes more time in Disc Utility and Onyx on my Macs than I've spent in diagnostic utilities of any sort for all of my non-server Windows machines in the same period.
My current pre-built
gaming PC's have not exhibited a single BSOD since purchase and the sole maintenance performed on them are the Microsoft / Antivirus updates. They get hibernated when not in use for quick wake-up and they're never rebooted unless they need it. The only thing which causes them to crash are games known to be unreliable. My regular PC's are even more reliable bar the Sony, which is perhaps slightly more unreliable than the Macs - probably due to bloatware I haven't bothered to remove / identify.
The Core (2) Duos + Quads / 51xx's - since my entire setup now consists of those CPU's - + Windows seem to be awesome for stability, even when seriously overclocked in the case of one of the Dells.
I wasn't exposed to the Gx's bar a Mini which made me consisder switching again - I started my Mac user period this time around with Intel Macs. The newest MBP (operating without any hardware additions bar a Wireless MM) had a GCOD on the third day after purchase in iPhoto of all things, even before I'd had a chance to install all the apps (but did manage to install all the updates). My first MBP, even sooner. My first Mac Pro, I think it was a week but it could be less. Seriously, I'm more than a little effed off. I don't actually go out to abuse these things - I use them to 'just work'.
I've used both Drive Genius and Tech Tool Pro 4 and have been satisfied but I've seen complaints about TTP4 on Intel-based machines. Since you're talking about Rosetta, I'd suggest going with Drive Genius or DiskWarrior.
Of course, check
VersionTracker or
MacUpdate before buying anything.
I'll have a look at those - thanks. I haven't actually tried the Tech Tool Deluxes that came with the Applecare - perhaps just as well.
Any other suggestions would be appreciated - no, not
those sorts of suggestions but ones pertinent to the original question
