Polished Wifi Sync App for iPad (Not Dropbox, SugarSync, Acrosync, ... )

Why is there no polished app on the iPad that allows syncing of files from your Mac WITHOUT the need for cloud?<p>I just bought an iPad and I would like to transfer 10gb of movies (some avi's, some from the internet) that I would like to put on my ipad. iTunes doesn't let me do that because you can't add avi files.<p>All I want is dropbox without syncing to the cloud (I don't need my avi files to be in the cloud. Moreover, 10gb+ will definitely go over my quota).<p>Any recommendations?
