This is why you get the 32GB model for the N10.1 so the thought of not having enough space for apps is not even the remotest concern. If you only have the 16GB model, you really have to use an SD card for photos, videos, music, and docs (because you may well need all your internal storage for apps). You should have no problem saving all of those things to the SD card -- at the very least, saving to the SD card is an option in the settings for most apps, and in some cases (like the camera), you'll be asked after putting in the SD card whether you want to save to the card.
