I received an R909 myself just a couple days ago. This is definitely the stop point for Sony...the rest just went downhill afterwards (except for the new R910 which is basically a R909 with N1 battery life). The large three line screen was a nice surprise coming from Sony, who traditionally used much thinner screens then Sharp. Sound quality is the usual stepped bass/treble, nothing new there. I'm digging it definitely...it goes right in with my Sharp 831/821/722 and Sony R50/E900/E95 now.
Looks like my N707 needs a new home now...
