That's one of Dave Watanabes dirty tricks. His apps are great, his marketing stinks.
Acquisiton is essentially just p2p software, while Xtorrent is the same thing, but uses torrent files, which means you can download torrents from websites, but also do a search among other users within Xtorrent.
It's faster, definitely, but not really good for small files (you won't find any). It's good for big stuff.
But remember, no piracy.
