faster int. hd question

[Malcolm Hamilton]

Hi all -
Has anyone on the list installed the 60GB 7200RPM internal hd 
(IBM/Hitachi Travelstar) in their powerbook?  I'm wondering if it 
speeds things up in any noticeable way.
Or, if you have lots of RAM, maybe the faster-spinning drive doesn't 
make much of a difference?
Any advice from someone who's tried the new drive, or knows about 
these things, would be appreciated.
Thanks,
Malcolm
