I really can't say anything about the Ovi Store infrastructure...

It's not only the download time, it is also the size of the meta data
that is stored locally and needs to be processed.  I am thinking about
making apt's cache updates fully incremental, so that the whole apt-get
update is proportional to the size of the pdiffs, and we also use pdiffs
for changes to /var/lib/dpkg/status...  But that's more on the crazy
side anbd the cache would still be quite big.

Anyway, the device should support pdiffs just fine.
