Well, what I came across on the Advantage was this - that video performance was relatively poor (inferior to Axim 51 or HX4700) because the device did not make use of its Imageon chip due to lack of appropriate graphics drivers.

htc advantage - video problem
and here
HTCClassAction.org - Because HTC dropped the ball, and it's about time they pick it up! (see the January 23, 2008 update).
So, it scared me off. I was going to buy this thing =it looks beautiful and has just the right form factor for me, but given the cost I can't just "take a chance" on the video performance, which is key for me.
Is there any way you could benchmark your Advantage using Coreplayer?
