Benchmarks "Earlier this week Apple released updated Mac Pros that use Intel's new Penryn processors. Also new is the fact that the standard Mac Pro configuration now comes with eight (instead of four) cores. Of course, what I've been wondering (as I sit here and think about getting a new Mac Pro) is how does the new standard eight-core Mac Pro perform compared to the old high-end Mac Pro? I've gathered Geekbench 2 results for both Mac Pros to find out."

This is not serious, especially these days that you have to save energy. An idle laptop uses at least 10 watts. Over several years, it does make a difference in a budget and it does not help the Earth.

And as some one else mentioned, if you don't reset your memory, after a week or more of uptime, your system will be slower because some applications are not optimized as they should be.

Mac laptops hibernate by default. Pull the power cord and battery if you want. In any case, Macs tend to sleep particularly efficiently: put it to sleep at 5pm, unplug the power cord; wake it up at 9am and plug it back in. It'll charge for a relatively short while, but you'll still have plenty of juice if you need to go wandering.

Restart your apps. My Macs only get rebooted when there's a significant software update, with no ill effects. A modern operating system shouldn't need rebooting just for the sake of ongoing housekeeping, and last I looked, none of the UNIX-based ones (including Mac OS X) do.

No, they don't. They go into sleep and will go further into hibernate mode if the battery charge falls under a certain level (you need an App like DeepSleep to make a Mac go into hibernate mode at once).
Nevertheless, this is waisted energy which is ridiculous just to "save" a few seconds boot time.

In any case, Macs tend to sleep particularly efficiently

You mean you waste energy particularly efficiently?
Your method of pulling the power cord is even more wasteful, since using the battery and recharging it is even less energy efficient and leads to battery degradation (use e.g. CoconutBattery and have a look at loading cycles and battery capacity degradation).

A modern operating system shouldn't need rebooting just for the sake of ongoing housekeeping, and last I looked, none of the UNIX-based ones (including Mac OS X) do.

The important word here is "shouldn't need". However, in reality, there is no such thing as a bug free OS. Unix based OS are normally used in server environments, where the amount of apps and services is mostly within a narrow range, the hardware is certified for a certain OS, is well tested under 7x24h conditions and the behaviour of the OS over time is known by the administrators (e. g. our industry grad OpenServer was rebooted every few weeks in order to prevent performance downgrading or unexpected reboots).

I guess the situation looks quite different when it comes to a "desktop" Unix. Sloppy programming, not very thouroughly tested drivers, hardware that was not meant for 7x24h usage, a whole bunch of services and apps, etc.

Do the environment and yourself a favour. Just shutdown your PC/Mac if you don't use it. No matter how capable or good your system is: waste stays waste.
