I am currently an Android user, looking to perhaps switch over to WP7. I am using an Atrix, which has 16GB on board storage, plus microSD expansion. Although the official specs for the Samsung Focus S have not yet been announced, it seems unlikely that it will have 32GB on board. Is there official word from anyone as to why no WP7 phones have so little storage, and have no expandable storage (beyond the original Focus)?
