Probably better to just piggyback a usb/sd card to the microUSB port when you need it. I haven't filled the 32GB on my Asus Transformer which is great for movies, nor my 32GB storage on the Thunderbolt which I use mostly for ROMs/Backups. Google Music's Cloud Storage really is great, but with carriers going to tiered data, again, isn't. I have unlimited, so I use a bunch of different clouds (the Sandisk is great, but needs some fine tuning to be faster on all phones).
lol.
