MY AIW 8500 came with the remote wonder, my AIW9800Pro came with the remote wonder 2 (as far as I can tell anyways, they are identicle in shape, size, button placement, colour). Both remotes are the same, the RW2 has a few extra lables on the buttons (Mute is labled ABC, 1 is labled GHI...etc and the left mouse button has a checkmark and right mouse has an X) but is functionally the same. Its supposed to be better for ATi's new EasyLook software... So far I've only seen the labels used once; upon closing the TV program via the power button it said "are you sure?" and had a picture of a checkmark and X...hitting the left mouse (also checkmark) meant yes. BTW I actually use my RW2 with my 8500 and my RW with my 9800.
I wouldn't worry about upgrading it but if you want a remote for another computer or a cheap Xmas present then get it, $15 shipping is cheaper then you can get the remote wonder for normally.
