More RPMs means faster access times. No news there.
When I upgraded my home laptop from a 2-year old MacBook Pro to one of the newly released unibody models, I decided to upgrade from a 5400 RPM drive to a 7200 RPM drive. I ran some bonnie-64 benchmarks and noticed a 40% improvement in random seeks/sec and some other impressive numbers. It's helped make my weekend hacking much more pleasant.
Here are the old numbers:
and the new numbers:
Bottom line: Recommended

I've been considering this upgrade myself. Bought the drive (with external case), did a backup, read the instructions... then put the project on hold while I bought a Torx screwdriver set and waited for urgent tasks to get out of the way first.
MBP 2.33 GHz for me. Did you have any problems?

I didn't replace the drive, I just bought a new MacBook Pro.

but how does it affect the battery life? I'd expect it to go down a bit since it takes extra energy to spin faster.
I'd like it to spin faster when encoding video, but if you are just web browsing on the train, then I am not sure if it works out so well. Does it always spin at 7200, or just "up to" 7200?

The battery life has been fine. I get about 3.5 hours, same as my old MacBook Pro with 5400 rpm drive.
