Uses for retired iPad 2

It looks like my iPad 2 that I bought on launch day is finally about to be put to pasture. Battery life isn't what it used to be, and the light leak from the screen is getting noticeably worse. I have ordered a replacement already, and it is time for this one to stop becoming my daily carry.

But, I don't want to just shelve it or sell it when there might be something useful that I could put it to use for. I have the HDMI adapter so I am thinking of maybe turning it into a media center type of thing? I was always afraid of jailbreaking, but now I am open to it. Any good jailbreak apps that could run while I leave it at home?
