Re: " ... which makes it about as useful as a non-existent rock"
I liked the bit about "complex web applications".. I think what they mean is badly written web applications :-)
I've noticed that in a lot of organisations you're better off having an application which needs a lot of resources and hand holding as management tend to think that this kind of application is important rather than realising that it is simply badly written and/or badly designed.
Managers also like the feeling that their applications and by extension they, are "special" and buying "special" memory feeds this rather nicely.
