as long as you aso have no need to dual boot, and as long as you are willing to wait the time for your memory image to be written to disk, etc

some people want their computer to actually shut off, so that they can use the power in the battery later when they turn it on rather than have it drain away in 'suspend mode'

the 'standby only' mode may be what you consider ideal, but many other people would not find it ideal, even if there were no bugs in the linux suspend

It's certainly possible some people want that, but I doubt there's _very many_ that go weeks
between uses of their laptop, on battery.

If linux power management worked as well on all the multitude of supported laptops/desktops, as
Apple has done for their 10 or so models, this conversation wouldn't be happening. Everyone I
know with a mac laptop simply closes the lid when they're done using it, no question. It's nearly
100% reliable and uses extremely minimal power.

well, if you can select exactly what hardware you will run on, supporting that hardware gets _much_ easier than the situation with linux where it needs to work on hardware designed by others.

it's not necessarily that people want to wait weeks between times that they use their computers, but if a battery will last a week on standby, letting the system sit in standby mode uses 1/7 of your power, that's a significant amount if you aren't going to be near a power outlet.

don't get me wrong, it's not that I don't want to see improvements in linux power management, it's just that I don't see 'suspend' replacing 'off' as being either realistic or desirable for all cases.

OS X still has bugs in this regard too -- I've seen 15" unibody MacBook Pros attempting to cook themselves in bags many times, with the lid shut.
