Xperia X1 free RAM

According to a review I read, Xperia X1 leaves me about 200MB free RAM
for application usage. This is a call for comments on how it behaves
in real-life conditions. Please, list what additional steps you took
that make your unit's state different from the way it is out of the
box (e.g.: list of additional applications you installed, original
applications you uninstalled or marked to be killed using certain task
manager (which one?).

Thank you for your comments.

Alex.
