The Logic Off Topic list

I've been using a pc with logic since 2000 and would like to update 
the program to stay current but i don't have a mac as of yet. Is 
logic a forever mac program now? Are there any big advantages to 
using the 2 together if i use logic for midi alone? I have a 24 trk 
hard disk recorder and i have a 24 channel mixer. I've always used 
logic for midi with a Unitor 8 since all my instruments are either 
keyboards or modules. I've never used any audio features of logic or 
any software synths. I'd be interested in any feedback concerning the 
differences.
Thanks
Gary
