Sony's been consistantly bad with supporting mac's in the past anyways. Their Clie's that run PalmOS have enough Sony in them that you can't even get them to HotSync with a Mac with out 3rd party software. The positive side of that negativity is taht hackers love to pley with Sony stuff (PSP!!) and it seems that alot of that is almost instigated because Sony trys to be so closed
So don't hold much hope that it will be Mac Compatible (at least not with out boot camp) but i do hope that the "Mod" community will take interest and open this reader up like an oyster.
