I agree, what ever size SSA sizes for you, you probably will outgrow it as
soon as you turn it on.  lol

I'm sure SSA is working with IBM to attempt to right size their products
together.  Unfortunately hardware does not come cheap, and if it runs slow
I'm sure their answer will be to buy a bigger box.
