This has to be the best way to track your stats on your Mac in one simple menu. Since I run a PPC 2.7Ghz Liquid Cooled G5 it is even more important to me.
Apple only made two LC Macs. There is always a chance that the LC could leak. That would start a domino effect in CPU temps. That is why I go to the IS menu and choose sensors and see all the temps on all the vital areas and fan speeds of my Mac. I can spot a problem in real time.
I have 3 drives (one is an external FireWire) with 6 partitions. Using Disk Usage tells me quickly how much space I have on each so I know where to save to.
To be ably to put together so many internal aspects together and in real time.
Now I am using the last PPC version of IS. In every version I discovered one major bug. When I would try to access the menu, it would fully freeze up and until it failed and it would rebuild the entire right side menu and itself back in the menu. Then I would get that the System UI crashed and I would relaunch it until the next time it would freeze. Yet the data I get makes it worth it even with the freezes worth it. Now I have yet to find any pattern to this Bug, it it happens randomly... Help
Over all, the learning curve is low, you can do a great deal of customization to the menu, deciding what elements you want under the menu all the data is in real time.
It has been around a relatively short period of time (in Mac yrs) so it has not had the time to see if it will make it. I think based on what it does and they follow the Apple guidelines, it should pass the time test. That only time will tell. In the meantime IS is an excellent utility and if you are the kind of person who wants to keep track of how your Mac is behaving then iStat Menu is the best out there. End of Line...
