(didn't mean to take this off topic...I'll just say my 2 cents and that's it)
I guess as long as it suits your need, it's fine. For a lot of users, I think their phone is the only camera they own so everything goes on it.
I'm kind of dissappointed because although I also only really need excess storage for pics and music, it puts limitations on other possibilities.
If you save emails or downloaded attachments, read offline newspapers, create offline maps (Google Maps option), many of these apps don't give you the option where to save data. On the older Droids/Froyo systems they automatically go to the SD card. On this phone (HTC) They go to the "internal" storage card......period!
I guess eventually, apps may give you more options where to save that data, or a new app to work around it, but for now it's such a waste of potential storage space (or the lack of ability to make that choice).
