preferences vs. customziation

[Ferenc Veres]

Hi,

http://wiki.openmoko.org/wiki/Category:Customization
http://wiki.openmoko.org/wiki/Category:Preferences

Do we need these two separated?

Maybe they are not dupes, but the similarity makes so difficult to put 
for example:

http://wiki.openmoko.org/wiki/Themes

in any of them. Maybe better description of which is what could help.

Thanks in advance,
Ferenc

ps: don't judge from parent category, that may be misplaced. ;-)
