Willcom D4 (Sharp WS016SH) accessories

The Willcom D4 (Sharp WS016SH) UMPC I purchased via special order through Conics is due to arrive next week, but until the Atom-based slider is in my hands, I can't help but continue to obsess over and look for more info about it.

Today, with the help of an email from Conics about my order status, I came across a list of all of its available accessories. In addition to the extended battery, which is included free for a limited time yet somehow missing from the list, there's the cradle (19,800 yen) we've known about since April, a GPS receiver (9,980 yen), Bluetooth handset (9,980 yen), RGB/USB cable (7,800 yen), miniUSB host connector (1,980 yen), and a handful of other peripherals. Additional pictures below.

I'm still looking for a case.
