How much internal storage for Apps does Nexus S have? I have a Nexus One now, and the internal storage is very limited. For the moment I have only 164 MB internal storage for apps (From DiskUsage).

Nexus One seem to have totally 512MB of internal storage. And Nexus S seem to have totally 16GB of internal storage. But Wikipedia wrotes: 16 GB iNAND (partitioned 1 GB internal storage,
15 GB USB storage

Does this mean that Nexus S only has less than 1GB of internal storage for Apps? I find my 164MB very limiting on Nexus One and I consider to buy a new phone because of this.
I believe the 1 GB is for the /system folder, which is not normally mounted via USB.  The rest of the space is usable for your apps!  I have a Galaxy S and this is how it works, plus there's an external SD card.
