What would you like in the next FW version?
I personally would like the photo interface to be improved - zoom would be really nice, and improved format support. A .txt viewer is really not rocket science, and would make the device useful for ebooks, game walkthroughs et cetera. Visualizations would also be a nice touch, and an option to change the sleep timer in addition to the screensaver, and (S610 only) an option to clear all the preset stations so when you select 'Auto preset', you don't have to delete the thirty presets manually. These would make this an absolute killer device.
