Trackball is a no go, and the G700 is simply too big hence the "mobile" description. Razer Orochi seemed almost perfect, but I've read some dreadful reports regarding it being pretty much useless for gaming over bluetooth because Razer have made so the mice goes into sleep / hibernate mode after just 2-3 seconds of idling when using bluetooth, resulting in lag every time this might happen during gaming.
But I do indeed love the idea of a wireless, gaming, bluetooth mouse, that would eliminate the need for adapter as well and the mouse itself looks stellar and seems quite mobile / portable.
Sadly it seems impossible to get in Norway these days, all suppliers and retailers claims it to be end-of-life and they're all out of stock. Importing one would make the shipping costing almost as much as the mouse itself making it a no go.
I've been looking at the Logitech AnyWhere MX, not gaming mouse by any stretch but seems to be solid performer on all surfaces because of the "darkfield" sensor and the size, design and everything seems to be stellar and it got Mac OS X driver support from Logitech, sadly it requires adapter but people seems to claim that Logitech unifying preform superior to bluetooth anyway.
