I tried my friend's macbook.  It's the white macbook that is 1.8Ghz and 512MB of ram, just normal usage of the laptop is slow.  Like websurfing can notice that is is slow.  If run browser with msn messenger chatting at the same time also slow, click on software to run, the start up time also slow.  The worst is to click to run office.  Super slow.  I wonder, I have always been a pc user.  Is this slow due to the lack of ram as the software used in macos is ram hungry?  My friend not yet install XP on his macboook yet, so I don't get to try how the macbook response in XP environment.  Would adding a ram help or boosting the CPU speed?  I like the macbook and thinking of getting one.  After trying with it, i like the interface and all, but just hate it as it is slow and makes me have to wait for every execution.
