I have tried only the two default themes, but I feel like the default default theme (the bloue one) is faster than the digital nature theme (orange). Although I like the orange better (I browse these forums all the time on my N900, so it matches the maemo theme nicely), I have now permanently switched to the default blue theme, it makes the N900 UI a much more pleasant experience.

Do you folks experience the same?

Dou you know of a theme that is optimized for UI speed?

All what's wrong with head yours?

i use default blue, it's the best
