What is your favorite system?

[okr]

DS at the moment.
Might be replaced by the Wii one day, when the library is larger and more diverse.

But I only own 4 consoles/handhelds, so there's not much competition in my personal list.

PC was my favourite in the 90s, but it wasn't hard to get the top spot then, as it was my only video game system until 2002.
