Fuji VS Fuji's well-organised Fujifilm X30 review is well worth the read. The review picks out several of the compounding interface inconsistencies across Fujifilm's camera line:

“The twist to turn on feature is clever, but this is one of those things I’ll have a hard time getting used to as the owner of multiple Fuji bodies. I always pick up the camera while fondling the shutter release, looking for the power switch. This is a non-issue for folks who only intend to own an X30 of course.”

as well as several of the improvements being made to the line, namely direct-selectable AF points:

“If you’re constantly changing your AF point and need to do it on the fly as fast as possible, Fuji has you covered. You can now set the D-pad to move the AF point immediately, rather than after tapping the AF button to activate. With this mode enabled, the functions listed on the D-pad are only accessible via drilling down into menu, or configured in your “Q” Menu.”
