This. I am never far from a power outlet, even when traveling. As long as my computer gets 4-5 hours of battery life, I'm set. Anything more is just gravy.

And let's not forget that 10.8.1 is still in beta, with more builds coming. If it fixes the problem for some people, that's a step in the right direction. If it doesn't fix it for everyone, it's obviously something they're working on and forthcoming beta builds should hopefully fix it for more people (and hopefully everyone).
Just because beta 1 of 10.8.1 didn't fix something for someone doesn't necessarily mean that the release version of 10.8.1 won't fix it.

I do too, I've never gotten anywhere close to their 7 hour estimates on my 2009 MBP. Even doing light tasks like reading websites and sending/receiving e-mail.
Why are OS X updates so huge? Assuming this ends up being 8GB like the rest of their 10.x.x updates. My Verizon LTE bandwidth quota is nearing and i wont be able to download this.
a) It'll probably be a delta update, so not nearly 8GB
b) Why are you using your phone to download operating system updates? If you must just go to Starbucks
People actually use the estimated time remaining? I never use it as it is completely context dependent. If you are running a ton of stuff, CPU at 100% it will show 2 hours. Running a web browser, 6 hours.
I find it much easier to determine how much time I have by looking at the percentage.
But I did find 10.8 to seemingly decrease the battery life of my Air.

All of the people saying that they've never seen the amount of battery life advertised for their machines are all folks with machines that came out before Apple changed their methodology for testing battery life, I've noticed.
But I'll say that I wish Apple had focused on "fixing" battery life in 10.7.1 to the same extent they are doing so in 10.8.1. My mid-2010 MBP took a significant hit in going to Lion, and I've never recovered from it.

I lost 3 hours of real time usage after switching from Lion to Mountain. My 2010 13" MBA went from 8 hours per charge to 5 hours per charge doing the same tasks. This is from a clean install* and redownload of apps from the Mac App store.
* installed ML, then booted from restore partition and reformatted SSD and redownloaded ML using Internet Recovery. About as clean of a clean install as I could do at the time.

My wife is a new macbook pro owner and was complaining about her battery life... only getting 3 hours or so.My rMBP barely lasts an hour and half
I looked at what she was doing and saw 2 flash videos being streamed, 2 more being buffered and she was rendering something in iMovie. Her fans sounded like my leaf blower.
So when is the fix to this train wreck being released? Is tomorrow a good guess?
My Early 2011 MBP13 went from 5.5-6 hours on Lion to 2.5ish on ML. Gets very hot and fans kick in at full speed every time I watch flash video (well, much hotter than on Lion). Even tried a clean install to no avail, so I await this update. Hopefully it'll be coming soon.

Not everyone lives where there is a Starbucks, or where there is highspeed internet...or a coffee shop every damn corner. Stop being a snob.
Hmm, that code change looks familiar (I guess it's not limited to battery programming)...
I am having the same exact problem with a Macbook Air 2011. It freezes up entirely when I'm on Chrome and the CPU starts to get fired up. I have to shut the whole thing down manually. But for some reason, I just can't give up using Chrome, if it is indeed the culprit.
Apparently most people do just that with their MacBooks - "reading an e-book with the screen on the lowest setting"
