I recommend the type cover. its a huge difference...although some people have trained themselves to use the touch cover; I still believe the typecover is much much better if you need speed typing.
I love the free classic games like minesweeper and shuffle party. You may need Slapdash for podcasts. There have been a lot of complaints of the xbox music app, but I like it. They have improved it to where its much more usable than when RT released.
You should also check out installing an SD card to expand your storage. There is a way to do it so that it recognizes the SD card as part of the library for your media.
Congratulations! Ive had Surface since launch, and I love it...and they keep making it better!
