I've gotta add my vote to the less impressed.

I'm not crazy about my Archos AV340, but I do think that the AV400 series is incredible. The build quality is actually professional for once (a new direction for Archos products), and it has twice the functionality of the photo iPod. You can record and play videos, and transfer photos with the built-in CF reader. The AV480 is slightly bigger, twice as heavy, and $70 more, but it has 20GB more and almost twice the diagonal screen size in addition to the built in card reader.

Everyone swoons over the iPod, though, so they can get by on just the aura of their product and this thing will sell.
