If it's considered "low-end" it's because people actually uses that
memory for something and the system starts swapping, not because it's
trendy.
The "powerful machines who never swaps" are always a minority. Being geeks
as we are we try to have the greatest machine possible, but the vast majority
of real users are "underpowered" I'm not talking of pentium 1 stuff, I can bet
there're far more pentium 4 machines with 256 MB out there than with 1 GB.
I know you don't hit those problems because you use expensive machines
with lots of ram ;) But in the _real_ world, lots of the machines are
already wasting most of its ram by running the desktop environment alone.
