No more USB mass storage? Darn, that was one of the main reasons I ordered a Nexus after trying another phone OS. Well, it's Linux so I suppose I can port Samba or NFS to it or something :-)
I actually looked into this once I found out the same about my Nexus 7. The workarounds all seem annoying at best. I just ended up installing a Windows 7 VM in order to make it less painful.
There is mtpfs, which mounts the storage over MTP using FUSE, but it's finicky. Since I have problems in Windows as well, I've been using FTP over Wi-Fi as much as possible, but it's quite slow compared to wired file transfer. So for large files, I'm still stuck hoping that it'll somehow work.
I use "Folder Sync". It runs on the phone, can be configured to start when on charger and on home wifi. will keep your phone synced with designated network shares.
That sounds like a good idea. The only issue would be that I'd have to get/set up Tasker/Locale with a wifi geofence, since I rarely bother connecting to my home wifi (instead of using 4G).
