This was being discussed in another thread already entitled is "my new macbook normal?."

I have a 2.0 GHz Aluminum MacBook with 4GB of Ram and the 160GB Hard Drive.

I have had mine for 5 weeks and it has 33 cycles on the battery and I know this to be correct. Aside from the fact that those numbers you mention sound normal; I wouldn't worry about your cycle count, but rather about your battery performance because you are not going to get a new computer or battery over 30-40 cycles being on a 5 week old battery (sounds completely within the normal range).

My statistics from iStat are: Health - 100%
Cycles 33.

My statistics from CoconutBattery are:
Current Battery Charge - 4274 mAh
Max Battery Charge - 4274 mAh at 100%
Original Battery Capacity - 4100 mAh
Battery-loadcycles- 33
Age of your Mac - 8 weeks (have had for 4 weeks).

From what I have gathered, the average mAh of a MacBook battery is around 4100 mAh. My MacBook battery lasts over 4 hours with backlight LCD at half power and internet being used constantly for updating football statistics at a sports bar using AirPort the whole time. I typically have 6 to 7 pages auto reloading at the same time. I am there from 12:30 to 4:15 and leave with 30+ min left in the battery indicator. Clearly the battery life is well beyond four hours without a heavy load on the CPU. Hope these numbers help determine if your battery is similar to mine.

hey thanks for your responses, i installed coconutbatteryand it says that my MBP is 3 months old!!! dude whats up with that haha

futch, you're numbers are very similar to my MBP's, so i hope you're right and everything is normal, i wasn't going to return it dude, i was just trying to figure out if it sounded right that i had 44 cycles on a 5 week use....i guess i should start using it plugged more instead of running it on the battery.

i've lost 1 % already from the health of the batt but i suppose that ok, hopefully....

thanks very much

That 1% loss isn't a bad thing and you will not notice a difference. I keep mine plugged in a fair amount too. I figure that if I am near the charger I might as well to save the battery.

I was referring to benzema24 about returning his MacBook because he referenced doing so in the other thread.
