Thanks for this informative comparison.
I'm very interested in WP8, and I'm more interested in the mid-range devices revealed so far like HTC 8S or Lumia 820 than the top of the range phones, partly because I prefer their smaller size and partly because of price.
The issue I have with these mid-range devices though, is the small internal storage provided (4 or 8 GB). It's not clear to me whether apps in WP8 need to be installed on internal storage or whether they can be installed onto SD cards. This is potentially an issue for me because there are a number of content heavy apps I have grown accustomed to have on my phone - specifically an offline encyclopedia app, an offline navigation app, and offline medical reference apps. In my iPhone, these apps collectively take up approx 5-6GB of strorage. If the apps do need to be installed on the internal storage, can the content be held on the SD card? Is it up to the developer of the app to implement this or is it under user control?
Could someone clarify where apps and content can be placed in WP8? The content I am unclear about is the specialist, perhaps proprietary, content in the type of apps mentioned above. I know things like regular documents, pictures, videos can be placed in the SD card.
Thanks
