Has anyone used the new G5 macs that run Windows XP?  If so, what do you think of 
performance in both OSX and WinXP?  Is it noticably less in either OS vs. a regular Mac or 
PC? I sampled one in a Mac store and noticed a definite sluggishness in mouse response 
when it was in XP but not in OSX. 

Thanks,
Bob R.
