Is ARM Ever Coming To the Desktop?

Where are the ARM powered desktops? I finally see some desktop models however they are relegated to "developer" models with USD200+ price tags (trimslice, etc). Raspberry Pi seems to be the only thing that will be priced correctly, have the right amount of features, and may actually be released.

Are ARM powered desktops destined to join the mythical smartbook?

Should Raspberry Pi become available, an ARM will end up on my desktop for sure.
