[comp.sys.mac.hardware] Memory & System 7.0

I'm thinking of increasing my memory and have
some general questions.  My current system is a IIci
with 4MB (four 1MB SIMMs in Bank A).

   1.  I've seen some advertisments for 2MB SIMMs for 
       "IIsi, LC, IIci" - I've heard that the IIsi
       can support 2MB SIMMS, but can my IIci??
       Somehow, I think that add was a misprint since
       similar adds for 2MB SIMMs don't mention the IIci.

   2.  If I were to use 2MB SIMMs, does that mean
       I can have (4 x 2MB) + (4 x 1MB) = 12 MB ??

   3.  System 7.0 supports Virtual Memory, so do I
       really need more that 4MB?  Right now my system
       (6.0.7) with all the INITs,etc.. takes up ~1.7MB
       so it doesn't leave me much to run several large
       applications at once. Will the Virtual Memory be
       efficient enough or will I see thrashing with a 
       large system (>2MB) and only 4MB?   

-Thanks
