EXS 24 Logic Sampler Users Group

I'm thinking about purchasing the EXS24. I have a PC PII, with 256ram 
and 9 gig sczi drive. I"m a new owner of Platinum 4.0. I don't know 
alot about samplers. I need to get feedback on the pro's and con's of 
the use of samplers in general and the pro's and con's of PC based 
samplers and Hardware samplers. 

Thanks in advance
