Hi,
i have the same situation...but i have just done one full recharge.
What i find a bit strange is that in the SystemProfiler the amount of amperage in mA is very high, it is about 2011 !!!. And what i see in the activation display is that there are only running two or three processes that are consuming more than about 0 % of the cpu. Bluetooth and the keyboard backlight are off, wlan is on. The batterie has a normal capacity of 4138 mAh
Having not done a complete time measurement yet, i would say the macbook lasts about 3-4 hours maximum. But the time remaining display increases and decreases very often, just opening only a browser.
Any suggestions about the high amperage?
Thanks in advance for some hints!
P.S.: the macbook model is 2.4ghz with 4 gb ram and 250 gb hd

Apparently the reason for this change was to make macbook lighter as a whole. Which is still a stupid reason.

Agreed.
Not too happy about my numbers right now, the capacity goes anywhere from 94-96%. I've calibrated about 5 or 6 times but the capacity seems to drop after each calibration.
That being said, I can still squeeze around 4-4:30 hours consistently out of my battery. I guess if it suddenly gets worse or drops below 80% capacity, I will take it in.
My advice to those of you who have a capacity over 4100 mAh is to be happy.

My MBP's battery has been playing up recently. The last few days it was only holding an hour's charge. I drained it and recharged it last night and now it's up to 1 hr 20 mins- this is after I turned off the keyboard backlighting, and the screen brightness to 3 notches from the top. Wifi is always connected.
Here are my coconut battery results. Perhaps it is just old and time for a new one? I have never got 5 hours like some others in this thread; 3 or 4 at the most. I usually have mail, safari, itunes/vlc open.
All opinions appreciated.

I get about 6.5 hours on my new white macbook with bluetooth off and screen brightness at about half.
Same, my new NVidia Whitebook battery seems amazing compared to the new unibody.
This is just using Firefox to read pages on teh Macrumors forums.
And this is what coconutBattery tells me.
(please note I've only actually owned this laptop for 9 days, not two months)
New Macbooks really do seem to be bad Batterywise, since the original capacity is actually 900mAh less than the new White Macbooks.
I extended the life of my battery by discharging the laptop totally on first use, and then leaving it turned off to charge all night. It extented it by about 300mAh so worked pretty well
I know this is a very late reply but I may be able to help other users here. I have 2 alu MBs (6 and 9 months old) and the battery life on both suddenly dropped from around 4 hours to 2 hours. Apple very kindly replaced one of the batteries and I paid to replace the other, which had done 300 cycles. However, both of the new batteries showed 2 hour lives after their first calibration.
After wasting ages trying to figure out why my batteries didn't have enough power, I followed the advice of 2 users on this thread and realized that the battery was irrelevant - the problem was that my MBs were both using far too much power.
On searching through Activity Monitor I found both computers had a "printserver" application running under another user's name, both eating up loads of power. Sounds like a virus to me. I managed to end both processes, although it took 3 attempts to force quit on the 2nd computer. Battery life remaining immediately tripled!
If you are using Activity Monitor, make sure you look for All Processes, not just the default My Processes - which doesn't show processes registered in the names of "other users", whoever they are.
I hope this works for others out there - I suspect it will. I'll now try and find out more about this printserver process.
