This depends on the amount of stuff you're running.  The nice thing
about Linux is that you're in control of how much fancy things you want
to run, and thus also roughly the amount of memory you want to commit to
that.  That said, Windows 7 is indeed rather hungry on memory,
considering under Ubuntu I need much less memory to have the same (in my
opinion) kind of visual experience.

Well, you should also defragment a Linux 'file system' (not 'hard
disk').  Probably EXT3 tries to avoid fragmentation, and maybe does a
better job at it than NTFS does?  I don't know if Windows (NTFS) users
need to defragment a lot?

I would definitely not say there is little standardisation? Linux is
Linux, it's the same everywhere, only the distro varies.  I'm no
security expert, but as far as I know no modern OS is in principle less
or more safe than another.  A truly unbiased security expert with
knowledge of different operating systems could probably enlighten us
more :)

Where did you get the idea that apps (in general) run faster in Linux???
The same program compiled on Linux or Windows should run equally fast on
the same hardware.
