The memory numbers sound normal. It's easy to misled by the many
different measures of memory usage in linux. A reasonable good overall
measure that will work whether you use KDE or GNOME is to open a
terminal, run the command 'free -m', and look at the number in the '-/+
buffers/cache:' row and 'used' column. For instance, on my desktop
$ free -m
total used free shared buffers cached
Mem: 2026 1878 147 0 73 1433
-/+ buffers/cache: 371 1654
Swap: 2047 33 2013
I see that I'm "using" 371MB of RAM.
BTW, RAM is cheap. Adding that second gig cost only $25.
