Well so far, it seems like quite the little unit, almost like an upgrade to the 323.
It seems to add a few of the feature requests which the DNS-323 lacks (seeing the people in this forum begging for certain things in FW upgrades for the 323), like FTP access, iSCSI initiator support, etc.
I'm sure Funplug will probably also run on it as well so you can install UPS-NUT tools which is another one I always like to add in.
Plus this one has a lot more memory (512mb), which I even remember somebody on the internet post a mod once where they literally soldiered on more memory to the motherboard of a 323, and then added the required hack to make it register the added memory.
The only thing I didn't see was any internal USB slot, so I may have to do like I did to my current 323 and soldier in the internal USB connector which runs off the unused USB controller chip, so I can install Funplug to run off of that.
It's as if Dlink KNOWS what they need to do to make these lower-end products rockin', but just wont add those features for USA release perhaps because it interferes with their other higher-end products which they can sell a lot more of here. Just a guess...
I always think that when I see low-budjet products offer enterprise functionality in countries with worse economies, where in our country where we can 'afford' to pay more for stuff, they force us to buy the enterprise business products if we want things like iSCSI etc...
