XI Playground - how much memory

Hello all,

beside i read all the sizing stuff,

my question is: How much memory does a Testcomputer need to have a nice System to Develop some Scenarios.

My first xi had 1,5 GB and that was a bit too less:-).

Actually a 640 Abap+J2ee Add in in my opinion for testing purposes should run nice with 2 Gbs...
