[maemo-users] Patriot Class 6 8GB or 16GB SD card?

[From: n800SanDiego at spamex.com]

I just ordered a N800 from Buy.com  during their Thanksgiving promotion ($190 USD).   I also ordered a iGo Stowaway keyboard from Amazon.com ($30 USD).  I'm looking forward to reciving it; I've wanted one of these since the 770 was introduced.

Now I need to select some memory.  

I've read the Patriot Class 6 16GB module works with the N800 but I think 8GB is probably enough for me.  Any reason I should get 16GB rather than 8GB?  Video storage, map caching, web caching?

Is Patriot memory a good choice?  Should I consider anything else?

Does 16GB draw more power and substantially drain the battery?
