How should I back up my iPad (1st gen.)?

I have a first generation iPad that isn't able to do much of anything except hold the information that's already there. There are tons of pics, videos and documents in pages. I am unable to connect to the internet, add a mail app or add any other apps. I have tried unsuccessfully to get assistance and this issue has seemed to stump everyone - including some associates at the Apple Store. What is the best way to transfer/move all of the data from the 1st Generation iPad? Would it be best to move it to either a newer iPad or MacBook? Also, this generation of iPads did not have icloud accounts so all data is directly on the device. I'm at my wits end on what to do and don't want to lose the data that's currently on the device over time.
