Yeah Zen had pretty horrible software, but it did its job pretty good anyways. One thing that really pissed me off about Zen was that I bought an expansion card when I ran out of the 8 gigs that it had (bought a 8 GB MicroSD, at least I think it was MicroSD, memory card, but it only worked like 30% of time and it was totally random when it'd work and when it wouldn't). Luckily digital camera used the same memory card type and was only 1 GB so the money wasn't wasted.
I got an Ipod now as well, and I like it much more, it's much easier and more intuitive to browse your music/playlists with an Ipod touch than it was with Zen, and I don't really hate ITunes that much either, and I never found it bothersome to sync my music. All you need to do is add all songs from your HDD (I just added my E:\Music) to the ITunes library. Then you check that "only sync checked songs" checkbox in sync options. Then you just check the songs you want to sync, and uncheck the ones you don't want to sync, and what makes this very easy is that you can use the browser to list all songs, or all songs by certain artist, or all songs of certain album etc. and you can then mass select/unselect checkboxes with ctrl+click, meaning that it's very easy to sync certain artist's music, or just one album etc.
I would love to sync my whole music folder, but 16 GB isn't nearly enough.
