Apple Logic Pro /LogicExpress Discussion

Thanks God we can talk freely about this topic here . My latest post 
about this on Logic users forum was "moderated" (rejected). They told 
me to tell those facts to Apple ( the fact that Logic5 on PC never 
crashes ). I told the moderator to tell himself ; he seems to heve a 
better relatioship with them ;-)

Nice to hear free opinions here , even if it´s sad to read about 
other people´s problems . I need to know if it worths to buy a G5 now 
or not. I´m still on 5.5.1 on PC , and I NEVER crashes and I´m using 
2 machines ( one Atlhon 1500 W98 and other PIV 2600 WinXP... FYI: The 
AMD system can run the same tracks/pluggins number the PIV system 
runs... but it´s almost half the speed... )

I tried my L7 on a  G4 450DP 512mb, but OSX and L7 seems too much for 
the machine . Any suggestion to make it work more like today 
standards will be appreciated ( more memory??? a processor upgrade??? 
both ?? none??? ) I´m new to macs.

Kind regards
