I do not think this kind of language is necessary or helpful. I suggest 
instead to ask Håkon why memory is such a concern for him. I suspect it 
has to do with Opera shipping millions of browsers on phones that are far
 more constrained than the first-generation iPhone, never mind a modern PC. 

More detailed and concrete background data on these constraints would
be interesting though.
